How stiff are the throttles on these boats

OK I have more experience with prop boats but the throttle on mine seems stiff its not smooth at all. It takes some force to move them and to bump the throttle a little you have to tap it with your hand you can't just lightly push it. My throttle on my prop boat is easily moved is this normal for these boats? Throttle cables where replaced in the last year and look brand new could they have been installed incorrectly?
 
I should add that neutral is very soft and the transition from neutral to forward or reverse is easy only tightens when applying throttle.
 
It's a totally different feel. Once you get used to it you won't notice it.
 
There are adjustments you can make in the throttle quadrant that can change the resistance. But as to actual motor response, I can't think of anything.
 
I suspect somethings not right, the throttle actuator is very easy and light to move, may be your throttles have a friction adjustment?
 
There are throttle tension screws on the rear of the throttle quadrant. You need to remove a small rubber plug to access them. It's very simple to do. Loosen the screws a couple of turns to see if that has any effect.

Are both throttles stiff? Try one at a time. Do you boat in salt water @robert843? Possibly the small rubber boots on the ends of the cable near the Jets have slid down or are missing.

Even though you mentioned they are smooth from neutral to forward & reverse I would still disconnect them at the thrust deflectors to determine absolutely if it's the control cable or the throttle cable. A little more digging will tell you what the problem is.
 
I doubt you have a problem. When comparing to an I/O boat the throttles are much stiffer. The new 242X has electronic throttles which eliminates this issue. I would assume Yamaha will pass this down to the other models soon. Unfortunately this will not help us.
 
one thing that takes a while to get used to (when compared to I/O's) is the transition from F-->N-->R is much smoother. Since there are no gears changing direction and just a bucket moving, these Jet's are very smooth.
 
Hmmm.... Changed my opinion on my first thought.
 
You should be controlling your speed with cruise assist when up on plane and docking. You should only move the throttles if you want to make a significant change in speed. The throttles are too sensitive to use them like an I/O. The cruise assist will help you with that.

It is possible your F-N-R cables are fine but your throttle cables are bound up. There are 4 cables that terminate in the throttle quadrant. You could try disconnecting your throttle cables at the motors and see if that reduces the friction but try the first steps I suggested first as they are easier. Where your cables always stiff since you acquired the boat or did it just start?
 
Cables have been like this since I had the boat. I was told they were replaced as the boat had been in salt water and looking at them you can tell they are new. I think it maybe as some mentioned I'm coming from a I/O boat and it was supper smooth you could easily push the throttle forward or reverse . Not the shifting of gears part but the actual throttle was smooth as you applied power. Mine just takes some force to apply power the actual bucket switch is smooth.

@robert843. It's very possible the previous owner had an issue where the throttle drops back causing him to tighten the friction screws on the rear of the throttle quadrant. It's only a 5 minute job to remove the rubber plug and give each of the 2 screws a turn or two counter clockwise to see if that resolves the issue.

When I back at the boat next week I will def give this a try.

I know a lot of people use this approach, but I am not a fan of it. When I am coming into a public launch I am either dodging people coming and going from the ramp or waiting for the ramp to clear. When waiting for the ramp to clear, I am constantly playing a game of F-N-R to hold steady or slow my forward momentum. While you can adjust the throttles to limit the lurching forward, jet boats still like to lurch forward a little. I also think controlling the boat via the throttle gives you more control than one of the (3) pre-programmed speeds you have with cruise assist. At minimum, if you are in tight quarters and are using cruise assist, you want to keep your hand on the throttle for any sudden adjustment you might need to make. I do love crusie assist in no wake areas though.

As far as throttle tension, even with adjustment, these boats have stiff throttles that are not smooth and easy like a traditional I/O. One of my few complaints.

I agree with you. I was suggesting using the cruise assist to keep the rpms up so the throttle would be more responsive while docking. I have no problem using elevated no wake mode rpms while maneuvering around the dock with F N R.

These boats have to be driven differently from I/O's. The throttle is very sensitive so it's just easier to use the cruise assist while cruising to adjust the speed.
 
I have had no issue with docking on this boat its actually been easier then my I/O with the twin engines and easy pivot points its pretty responsive. Same at low speed I see no need to get fins as I do not mind it at all at low speed. What I was looking for was that smooth throttle up from the I/O it seems that to go from a slow speed to cruise speed I really have to force the throttle up compared to the I/O I'm sure that is fixed with the newer boats with the electric throttle from the cable.

Agree 100% that when you are on the lake using the +/- on the cruise assist is the best way to not only manage smooth acceleration and deceleration, but it also keeps the RPM's of both motors consistent.

Where are the friction screws you talk about here? I unwrapped the boat for the season and all of a sudden the starboard throttle is super stiff. I lubed the bucket and and tried to shoot some lub in the cable down by the jet pump. Any ideas would be greatly appreciated.
 
@Flower Not sure about the 2015s but I suspect it's the same as mine - on the back of the throttle (the 'reverse' side) there are two plastic covers down near the bottom. These cover the adjustment screws. (See image from 2012 service manual.)
