Very important no nonsense information when deciding what aftermarket steering system to purchase. Cobra jet steering has a system to meet your needs.
Yamaha has several newer style jet boats equipped with an articulating keel. We add indicators in the name to make you aware of their compatibility to indicate what version will work with your particular boat. The indicator “ AK”in the name means it is for boats with articulating keels, “AK-19” means those systems are compatible with the boats built from 2019 and newer as those have the articulating keel and the new nozzle and reverse bucket design that began in 2019 thus AK-19.
The boat hulls have two different types of Articulating keels so when ordering for a single engine boat you will be informed that it is for a single engine only and there will be no twin engine set offered likewise for the twin engine systems there will be no single engine set offered.
If there is no designation it indicates the system is compatible with all NON articulating keel models, “prior to 2015 on the 24-foot models”, “prior to 2016 on the 19-foot models”, “prior to 2017 on the 21-foot models”
For example, the “super ultimate system” no designation in the name so it fits ALL Yamaha jet boats single engine and twin-engine versions prior to the above-mentioned model year for each hull size and both single engine and twin-engine versions are offered. Once we get to the AK and AK-19 models they require a designation for twin engine systems as those are not cross compatible. The twin version will say twin engine.
Now second example, let’s say the system is a super ultimate AK-19 That would be for a 2019 or newer boat however there is NO twin-engine system indicator so it is for the single engine 19 foot only.
There will often be upgrades or upgraded levels for each of the systems. That information will be available when and where you view the system information.
Not sure what year your boat is? It is easy to confirm the year of your boat, it is the last two digits of your hull ID number. It will be on your registration as well. Also, when you place an order, we always ask for the boat make, model and year so we can check on the parts you ordered and notify you if there is any question before shipping the order.
Next if you are not sure if your boat has an articulating keel, here are pictures of both.

Single engine articulating keel started in 2016- twin engine 24 foot in 2015- and 21-foot twin engine in 2017.
First let us address the twin engine Yamaha articulating keel jet boats. From 2015 and newer on the 24 foot boats and 2017 and newer on the 21 foot boats Both models use the same Super Magnum AK systems.

note second tie rod and V configuration of the fins way above the rudder.
The nozzles were redesigned in 2019 on all the Yamaha jet boats. So we have systems modified to fit the original nozzles the new style nozzles and the articulating keel models both single engine and twin engine. these are super magnum AK-19 systems 19 indicates the first model year of the new nozzles.

And now the latest deluxe version with top fins for huge slow speed steering improvements as well as a modified fin bracket to produce a planing effect for improved hole shots and provide a more stable ride in chop.
Top fins are designed to provide extra steering control only when the hull is off plane, when the hull is on plane the top of the super fins as well as the entire inner top fin is up out of the water!
and another super magnum AK-19+

. recent picture of super magnum ak-19 deluxe with ak fangs on a new Yamaha 252SD
All the newer model twin engine Jet boats have a large keel down the center of the hull, this keel acts like a fixed rudder to keep the boat tracking straight to help guide it on plane.
The down side to this is ,the keel wants to keep the boat going straight even when you want it to turn, the faster you go the more it resists turning.
Yamaha added a rudder to the back of the keel to help with the steering , it's a fairly large rudder but it still leaves a lot to be desired .
Also this rudder causes a lot of resistance in the helm so Yamaha uses a rack and pinion steering helm to allow the steering wheel to turn easier however this is a trade off as it requires twice the steering wheel travel.
A full turn to the left or right from center on a regular helm was about 1/4 turn, it is now 1/2 turn , so from full right all the way to full left is about 1 full rotation of the wheel.
Simply put its geared down making it feel easier to turn.
The increased work load has not changed and it is tied into just one nozzle, thus placing all that extra resistance on one side and all on one cable.
Although the nozzles are very rugged and the steering can take the load we believe it only makes sense to balance out this work load sharing it between the two nozzles and cables for added longevity improved reliability and redundancy?
The extra tie rod also removes the nozzle play and allows you to easily set a slight tow in on the steering to provide straight tracking at speed.
Even with the rudder added to the regular steering nozzles if you rapidly decelerate during a turn you can completely lose your steering control , if you own one of these boats you probably already experienced this.
I call it off power steering and you will gain off power steering with several of the cobra systems . Even with the factory rudder, if you are rapidly decelerate while turning people report losing all steering control . People also report a large bleed off of speed while attempting to make high speed turns. All this can be disappointing and even dangerous during water sport activities or in heavy traffic areas.
Our Super Magnum A K and our Super Ultimate A k steering systems address these issues and our AK Mega fang plus upgrade on either system will make you think you have a different boat. Steering at all speeds and off power, enhanced turning capabilities with much less bleed off in the turns.
Super Ultimate AK system on a customers boat, big difference is these are larger , spring loaded and can be set to retract at speed or stay down all the time.

NEW Super Ultimate AK-19 deluxe twin engine
Next is reverse control or lack thereof.
The keel and rudder provide very little reverse steering. This may not be your primary concern but it is important to be able to back your boat with accuracy, predictability and power. Especially when dealing with off loading your boat or in heavy traffic areas as well as wind and currents effecting your reverse control.
We can provide you with real reverse steering and reverse control , with twin engine boats turning the back of the boat sideways in place is accomplished by staggering the controls, this feature is already in your stock twin engine twin throttle jet boat, try it yourself .
With our mega fang plus upgrade you can enhance that feature as many people have reported along with more usable reverse thrust for better stopping power and better control in reverse against wind and current and heavy boat traffic areas.
At Cobra Jet Steering LLC we have been fixing the steering deficits on jet boats and p w c s with affordable patented retrofit-able steering systems since 2001. We build steering based on our experience and customer input.
Our Super Magnum A K adjustable effect steering system designed for the twin engine articulating keel Yamaha jet boats addresses the steering shortcomings at ALL SPEEDS! Not just at IDLE speed. AND YES OFF POWER STEERING ALSO ! And lets not forget water sport activities need that extra steering response and control as does rough water conditions and heavy boat traffic areas.
The Super Magnum A K system provides instant steering response to the helm so completely that you may forget you are driving a jet boat.
This system also addresses the uneven work load of the original factory steering system by adding in a second tie rod to balance out the steering providing a push/pull force when turning in either direction. This also adds in redundancy to your system.
We position specially designed 6061 t6 aircraft aluminum steering fins off to the side of each nozzle directly in the flow of water as it passes the hull for more balanced and effective steering in a V configuration without creating huge obstructions hanging way down or all over the back of the boat!
Once again providing more control with less obstructions than other systems.
We also provide the option of a conservative set of A K fangs that mount on each steering fin to provide some power steering and some improved reverse influence at a very modest price, OR you can choose the MEGA FANG PLUS SYSTEM for the MAXIMUM effect!
This system provides improved reverse control by channeling the water as it exits the reverse opening of the steering nozzles. This channeled force will move your boat around while backing like never before, customers have described it as good and even better than a prop boat for reverse steering and it will not require any special training or even practice to operate.
If you have operated prop boats in the past you will enjoy having reverse steering like it is supposed to steer.
Additionally the Mega Fang plus enhance both reverse and forward steering.
The Mega Fang plus system was designed to corral and use more of the enhanced reverse thrust for improved stopping power and better power when backing of the trailer or lift as well as improving the stopping power of the reverse thrust when you need to stop quickly.
The mega Fang plus upgrade also provides a nice power steering effect by extending forward of the nozzle pivot point to actually reduce the work load of your steering system.
And now it's 2020 so we have some upgrades to offer for the magnum AK and AK-19 customers past and present in the area of upgrades to current systems or upgrade levels for the new customers.
First on both the versions of super magnum steering you can obviously upgrade to the super fins, however now you can also upgrade to ad the top fins to both systems and you can upgrade to add the plaining surface fin brackets , these upgrades can be done together or separately, simply contact me directly for more information.
So when it comes to choosing steering for your Yamaha articulating keel twin engine jet boat you can SPEND the MOST MONEY or GET THE MOST for your MONEY it's your call! Each year jet boats are filling the boating requirements of more and more people, and we are meeting their requirements for more steering response and control.
Next let us discuss the Cobra Super Ultimate Steering System for all Yamaha single and twin engine jet boats prior to the articulating keel models as well as our newest version the Super Ultimate A K steering for the 2015 to 2018 models with twin engines with articulating keels and the latest SUPER ULTIMATE AK-19+ for 2019 and newer twin engine articulating keel boats as well as Super Ultimate ak-19 system for the single engine 2019 and newer models.
The Super Ultimate system is our best selling most popular steering system . Now we have it for the entire lineup of Yamaha jet boats and we have upgrades available as well.
You have the basic system or the newest with a larger top fin and the option of a plaining surface side force stabilizer , these upgrades can be added individually just like the super magnum upgrades. So there is the super fins , the top fin, and the plaining side force stabilizer now available. Here is the latest SUPER ULTIMATE AK-19 DELUXE
Twin engine=
single engine= 
twin with mega fang plus=
Single engine super Ultimate AK with new version of the mega fang plus =
the lower fang clears the rudder and keel. you may also wish to upgrade to the new side force stabilizer that also provides a plaining surface on AK and AK-19 models= note AK 19 models are not compatible with mega fangs.
The Super Ultimate steering is unique because it incorporates spring loaded, adjustable fins for varying influence that can be changed to meet the requirements of the boat operator even if those requirements change from time to time.
This adjustment on the twin engine boats each fin is independently adjustable.
Also these fins can be set to stay down all the time at all speeds or set to rise up at speed if you choose. So when you add our The Super Ultimate system it allows you to decide what it does and how it does it.
There are Super Ultimate Systems compatible with all single engine Yamaha jet boats , Twin engines up to the model year 2018.
Twin engine 24 foot model years 2015 through 2018 are covered by our new Super Ultimate A K system or our Super Magnum A K system. For 2019 and newer twin engine models the Super Magnum AK-19 steering systems are currently available .
These are specially designed and include the second tie rod for balance .
All Super Ultimate steering is made 3/16 thick laser cut 6061- T6 aluminum. This material provides excellent strength , durability and effectiveness without creating any unnecessary drag on the system .
They are also compatible with the MEGA FANG plus for power steering / power stopping / Excellent reverse control & off power steering.
The Ultimate steering system has so many options and features built in that nothing on the market can compare with it. It is The only system that does it your way at your level even if that changes from time to time.
Coupled with the Mega fang plus you can steer a 24 foot non rudder equipped Yamaha jet boat in an S turn while rapidly decelerating from a planning speed.
For a jet boat with no additional rudder just the nozzles turning, the old rule is no thrust no steering but that goes out the window with our systems installed.
So steering the boat in an S turn off power was totally unheard of until we came along and changed how jet boats handle !
Very important no nonsense information when deciding what aftermarket steering system to purchase continued.
So now we will take a look at the COBRA VIPER system because people seem to get addicted to this one on the 19 foot boats.
Obviously we have one for each style , keel setups / non keel setups / early nozzles or late model nozzles.
Note mega fang plus upgrade is available for all vipers As is the top fang upgrade . Note the new 2019 and newer nozzles are NOW compatible with the VIPER AK-19+ steering systems. Just as we planned we now have a compatible VIPER available in early 2020. And it is also compatible with the top fangs upgrade just as ALL the VIPERS are.

top fang upgrade for ALL styles 
Viper for NON keel boats with both forward fangs and top fangs
. viper ak-19+
and with top fangs
The VIPER steering has fins that are spaced wider apart for more travel to provide more steering effect while making the fins with less depth, this is very important as single engine boats have the pump and nozzle lower to the ground than a twin engine model.
So rather than have fins hanging down far below the hull we decided to build a planning platform that places the fins away from the lowest part of the boat , This design helps the boat get on plane sooner and stay on plane at a slower speed, it helps stabilize the hull in rough conditions and it improves all the steering from slow and idle speeds in forward and reverse to wide open throttle.
When rapidly decelerating it holds the boats direction nicely and when on plane it also holds the boat on course without constant need for steering input.
All VIPER systems have forward leading front fins similar to fangs improved reverse control and add a power steering effect all in one simple inexpensive system . Adding Extra fangs greatly increases that effect.
Also the VIPERS made for the non keel boats " note the NK or NK2 versions" may also add the Mega fangs plus upgrade for an additional 85 dollars and amp up the steering / stopping / reverse and power steering effects on their viper system that will more than make up for not having the keel. And our newest TOP FANGS are compatible with ALL VIPER MODELS.
The Top Fangs add a larger surface to the viper that is above the bottom of the nozzle so that it works like the Super fins adding more influence when operating in no wake or idle speeds in forward and reverse .
When the boat is on plane this extra influence is not needed and automatically out of the water.
Just one more way we help put you in control and put a smile on your face, it is what we do .
Very important no nonsense information when deciding what aftermarket steering system to purchase continued.
Now we can discuss the 4 tec steering system I build for the Sea Doo / Scarab / Chaparral and Glastron boats using the 4 tec engines and pumps.
This is a very different situation as these boats have an excellent factory reverse system built in.
Once you learn to look at the front of the boat and decide where you want it to point and then just turn the wheel in that direction you can quickly overcome the reverse confusion since the steering in reverse is opposite to what we are accustom to while driving a car or prop boat.
This setup uses a large reverse bucket that is fixed so it does not move with the nozzle.
The nozzle turns inside this reverse bucket redirecting the reverse thrust out different ends of the bucket.
The trick is to provide steering influence in forward to allow the boat to be predictable and responsive without taking away from the reverse handling.
It is important to understand that I drive p w c s that have the same reverse and on my p w c s I can turn on a dime in reverse do a creep forward or backward I have fun with this feature.
So when I built steering for these boats I knew what I needed to do and what I needed to avoid at all cost.
The Sea doo 4 stroke systems have been around for many years I build a system that uses very small number 10 stainless screws to attach it to the nozzle, the system is stainless also, I could build very fancy and expensive systems just look in my patents and see for yourself.
That being said These boats do not need nearly the amount of assistance that the Yamaha setups need, so why mess with success?
I build a system that I even offer to install on your nozzles at no extra charge if you send them to me just in case you get squeamish drilling some very small holes in your nozzles.
So here are the facts ,these nozzles are some of the strongest I have ever dealt with right up there with the Mercury Optimax nozzles.
Drilling a few small holes does nothing to damage or compromise the nozzle , and it WILL NOT affect your WARRANTY! Actually none of my steering products will void your warranty on any make boat.
In all the years I have been doing this I have NEVER seen a single 4 tec nozzle broken by adding these fins even when impacting a solid object., once someone experiences driving with this system on their boat they won't take them off.
Interestingly the nozzles brand new can be purchased for around 70 dollars on line if you ever did need one so no worries .
However I have never heard of anyone needing a new nozzle.
The systems provide instant slow speed response to the helm plus they provide high speed enhancements and the way I designed them they do not interfere with the reverse steering as most of the actual fins are shielded by the reverse hood when backing up so they don't provide interference. They do not cause water spray or rub on the reverse hood either.
The system is made to work on both the single engine or the twin engine setups so it is the same price either way because it is the same system it just mounts differently.
Two on a single engine and one per nozzle on a twin engine.
So if you want some nice predictable and effective all time steering assistance for better all around handling and improved handling during water sports or in rough conditions we have real steering that will spoil you and let others drive with confidence as well.
//////////////////////////////////////////////////////////////////////////
So let's talk about exactly what a mega fang plus set is , how it works , what it offers you in the way of features and benefits and why it is so effective on a Yamaha jet boat.
Mega fang plus systems are a larger version of the original fangs, the larger size enhances all the effects.
First the power steering effect.
For centuries mariners employed a simple principal when turning a rudder on a ship .
Rudders create directional drag to change the direction a ship or boat is traveling , drag on the right vessel turns to the right etc. This however does create some resistance and when they used a tiller attached directly to the rudder it could be next to impossible to turn the rudder in bad conditions.
So they discovered if they placed part of that rudder forward of the pivot point the boat traveling through the water could harness some of the energy of the water and use it to help turn the rudder, thus allowing one person to steer the vessel as it greatly reduced the work load required to defeat the water resistance. Mega fangs places small fins under the nozzle where they can capture some of the energy of the boats forward movement thus reducing the amount of effort needed to turn the steering system, especially at higher speed.
It is also important to understand that not only are steering fins, factory rudders etc. responsible for resistance at higher speeds but the jet system itself is a major contributor to this resistance.
The jet pump is producing a huge amount of liquid thrust sufficient to propel your jet boat at some pretty impressive speeds, just imagine the amount of force that is being expelled from the nozzles.
The water jet is trying to keep your steering nozzles perfectly straight, so when you turn the nozzle via the steering wheel you are fighting that force and it is fighting you.
Now the mega fang plus system jumps in to counter a portion of the total resistance allowing for you to turn the wheel easier.
Next we can focus on the enhanced stopping power and reverse thrust for backing off trailers and boat lifts.
The Mega fang plus location and forward positioning also focus the reverse water exiting the bottom of your nozzles. Since Yamaha reverse just shoots the thrust under the nozzle by closing off the water's normal exit out the back and redirecting it under the boat in a forward direction causing the thrust to push the boat in an opposite direction , as the nozzle turns from one side to the other it changes the direction of that thrust supposedly creating a directional steerage however it is usually inadequate for most people.
The Mega Fangs are located on either side of the nozzles reverse water exit , this allows them to direct and focus the thrust giving it more power and more steering effect combined with the steering fins so it now steers in reverse more like a conventional boat .
Now the steering system enhancement.
At planning speeds the Mega fang plus will actually capture water flowing under the nozzle and turn into it using their power steering effect to move the back of the boat sideways as the steering system is also moving the hull .
An example is the steering system is pushing the front of the boat to the right while the Mega fangs are pulling the back of the boat to the left creating a very impressive and effective steering response. Imagine someone paddling a canoe on one side only to get it to change direction while another person in the back paddles backward on the opposite side of the canoe. That is about the best way I can explain it.
So I provide you with all these important features and benefits, I sell the systems for a very competitive price. And I guarantee you will like it or you can return it within the 30 day period for a refund . Remember this is what I do, my goal is to make your boat easy and predictable to operate and make you smile when you get behind the wheel.

the lower fang clears the rudder and keel. you may also wish to upgrade to the new side force stabilizer that also provides a plaining surface on AK and AK-19 models= note AK 19 models are not compatible with mega fangs.The Super Ultimate steering is unique because it incorporates spring loaded, adjustable fins for varying influence that can be changed to meet the requirements of the boat operator even if those requirements change from time to time.
This adjustment on the twin engine boats each fin is independently adjustable.
Also these fins can be set to stay down all the time at all speeds or set to rise up at speed if you choose. So when you add our The Super Ultimate system it allows you to decide what it does and how it does it.
There are Super Ultimate Systems compatible with all single engine Yamaha jet boats , Twin engines up to the model year 2018.
Twin engine 24 foot model years 2015 through 2018 are covered by our new Super Ultimate A K system or our Super Magnum A K system. For 2019 and newer twin engine models the Super Magnum AK-19 steering systems are currently available .
These are specially designed and include the second tie rod for balance .
All Super Ultimate steering is made 3/16 thick laser cut 6061- T6 aluminum. This material provides excellent strength , durability and effectiveness without creating any unnecessary drag on the system .
They are also compatible with the MEGA FANG plus for power steering / power stopping / Excellent reverse control & off power steering.
The Ultimate steering system has so many options and features built in that nothing on the market can compare with it. It is The only system that does it your way at your level even if that changes from time to time.
Coupled with the Mega fang plus you can steer a 24 foot non rudder equipped Yamaha jet boat in an S turn while rapidly decelerating from a planning speed.
For a jet boat with no additional rudder just the nozzles turning, the old rule is no thrust no steering but that goes out the window with our systems installed.
So steering the boat in an S turn off power was totally unheard of until we came along and changed how jet boats handle !

So now we will take a look at the COBRA VIPER system because people seem to get addicted to this one on the 19 foot boats.
Obviously we have one for each style , keel setups / non keel setups / early nozzles or late model nozzles.
Note mega fang plus upgrade is available for all vipers As is the top fang upgrade . Note the new 2019 and newer nozzles are NOW compatible with the VIPER AK-19+ steering systems. Just as we planned we now have a compatible VIPER available in early 2020. And it is also compatible with the top fangs upgrade just as ALL the VIPERS are.
non keel
keel model top fang upgrade for ALL styles Viper for NON keel boats with both forward fangs and top fangs
. viper ak-19+ and with top fangsThe VIPER steering has fins that are spaced wider apart for more travel to provide more steering effect while making the fins with less depth, this is very important as single engine boats have the pump and nozzle lower to the ground than a twin engine model.
So rather than have fins hanging down far below the hull we decided to build a planning platform that places the fins away from the lowest part of the boat , This design helps the boat get on plane sooner and stay on plane at a slower speed, it helps stabilize the hull in rough conditions and it improves all the steering from slow and idle speeds in forward and reverse to wide open throttle.
When rapidly decelerating it holds the boats direction nicely and when on plane it also holds the boat on course without constant need for steering input.
All VIPER systems have forward leading front fins similar to fangs improved reverse control and add a power steering effect all in one simple inexpensive system . Adding Extra fangs greatly increases that effect.
Also the VIPERS made for the non keel boats " note the NK or NK2 versions" may also add the Mega fangs plus upgrade for an additional 85 dollars and amp up the steering / stopping / reverse and power steering effects on their viper system that will more than make up for not having the keel. And our newest TOP FANGS are compatible with ALL VIPER MODELS.
The Top Fangs add a larger surface to the viper that is above the bottom of the nozzle so that it works like the Super fins adding more influence when operating in no wake or idle speeds in forward and reverse .
When the boat is on plane this extra influence is not needed and automatically out of the water.
Just one more way we help put you in control and put a smile on your face, it is what we do .
Very important no nonsense information when deciding what aftermarket steering system to purchase continued.
Now we can discuss the 4 tec steering system I build for the Sea Doo / Scarab / Chaparral and Glastron boats using the 4 tec engines and pumps.
This is a very different situation as these boats have an excellent factory reverse system built in.
Once you learn to look at the front of the boat and decide where you want it to point and then just turn the wheel in that direction you can quickly overcome the reverse confusion since the steering in reverse is opposite to what we are accustom to while driving a car or prop boat.
This setup uses a large reverse bucket that is fixed so it does not move with the nozzle.
The nozzle turns inside this reverse bucket redirecting the reverse thrust out different ends of the bucket.
The trick is to provide steering influence in forward to allow the boat to be predictable and responsive without taking away from the reverse handling.
It is important to understand that I drive p w c s that have the same reverse and on my p w c s I can turn on a dime in reverse do a creep forward or backward I have fun with this feature.
So when I built steering for these boats I knew what I needed to do and what I needed to avoid at all cost.
The Sea doo 4 stroke systems have been around for many years I build a system that uses very small number 10 stainless screws to attach it to the nozzle, the system is stainless also, I could build very fancy and expensive systems just look in my patents and see for yourself.
That being said These boats do not need nearly the amount of assistance that the Yamaha setups need, so why mess with success?
I build a system that I even offer to install on your nozzles at no extra charge if you send them to me just in case you get squeamish drilling some very small holes in your nozzles.
So here are the facts ,these nozzles are some of the strongest I have ever dealt with right up there with the Mercury Optimax nozzles.
Drilling a few small holes does nothing to damage or compromise the nozzle , and it WILL NOT affect your WARRANTY! Actually none of my steering products will void your warranty on any make boat.
In all the years I have been doing this I have NEVER seen a single 4 tec nozzle broken by adding these fins even when impacting a solid object., once someone experiences driving with this system on their boat they won't take them off.
Interestingly the nozzles brand new can be purchased for around 70 dollars on line if you ever did need one so no worries .
However I have never heard of anyone needing a new nozzle.
The systems provide instant slow speed response to the helm plus they provide high speed enhancements and the way I designed them they do not interfere with the reverse steering as most of the actual fins are shielded by the reverse hood when backing up so they don't provide interference. They do not cause water spray or rub on the reverse hood either.
The system is made to work on both the single engine or the twin engine setups so it is the same price either way because it is the same system it just mounts differently.
Two on a single engine and one per nozzle on a twin engine.
So if you want some nice predictable and effective all time steering assistance for better all around handling and improved handling during water sports or in rough conditions we have real steering that will spoil you and let others drive with confidence as well.
//////////////////////////////////////////////////////////////////////////
So let's talk about exactly what a mega fang plus set is , how it works , what it offers you in the way of features and benefits and why it is so effective on a Yamaha jet boat.
Mega fang plus systems are a larger version of the original fangs, the larger size enhances all the effects.
First the power steering effect.
For centuries mariners employed a simple principal when turning a rudder on a ship .
Rudders create directional drag to change the direction a ship or boat is traveling , drag on the right vessel turns to the right etc. This however does create some resistance and when they used a tiller attached directly to the rudder it could be next to impossible to turn the rudder in bad conditions.
So they discovered if they placed part of that rudder forward of the pivot point the boat traveling through the water could harness some of the energy of the water and use it to help turn the rudder, thus allowing one person to steer the vessel as it greatly reduced the work load required to defeat the water resistance. Mega fangs places small fins under the nozzle where they can capture some of the energy of the boats forward movement thus reducing the amount of effort needed to turn the steering system, especially at higher speed.
It is also important to understand that not only are steering fins, factory rudders etc. responsible for resistance at higher speeds but the jet system itself is a major contributor to this resistance.
The jet pump is producing a huge amount of liquid thrust sufficient to propel your jet boat at some pretty impressive speeds, just imagine the amount of force that is being expelled from the nozzles.
The water jet is trying to keep your steering nozzles perfectly straight, so when you turn the nozzle via the steering wheel you are fighting that force and it is fighting you.
Now the mega fang plus system jumps in to counter a portion of the total resistance allowing for you to turn the wheel easier.
Next we can focus on the enhanced stopping power and reverse thrust for backing off trailers and boat lifts.
The Mega fang plus location and forward positioning also focus the reverse water exiting the bottom of your nozzles. Since Yamaha reverse just shoots the thrust under the nozzle by closing off the water's normal exit out the back and redirecting it under the boat in a forward direction causing the thrust to push the boat in an opposite direction , as the nozzle turns from one side to the other it changes the direction of that thrust supposedly creating a directional steerage however it is usually inadequate for most people.
The Mega Fangs are located on either side of the nozzles reverse water exit , this allows them to direct and focus the thrust giving it more power and more steering effect combined with the steering fins so it now steers in reverse more like a conventional boat .
Now the steering system enhancement.
At planning speeds the Mega fang plus will actually capture water flowing under the nozzle and turn into it using their power steering effect to move the back of the boat sideways as the steering system is also moving the hull .
An example is the steering system is pushing the front of the boat to the right while the Mega fangs are pulling the back of the boat to the left creating a very impressive and effective steering response. Imagine someone paddling a canoe on one side only to get it to change direction while another person in the back paddles backward on the opposite side of the canoe. That is about the best way I can explain it.
So I provide you with all these important features and benefits, I sell the systems for a very competitive price. And I guarantee you will like it or you can return it within the 30 day period for a refund . Remember this is what I do, my goal is to make your boat easy and predictable to operate and make you smile when you get behind the wheel.
