Will a 2017 1.8 liter non supercharged fit my boat

[Keeway]

I have a 2015 ar 195 supercharged I blew the engine , wondering if I bought a non supercharged 1.8 liter will it work , and is will my supercharger bolt onto that engine ??

 

[SamCF]

It will bolt in, but it won't work in your boat. The engine has different internals that can not handle the supercharger.

How is the engine blown? What is wrong with it?

If you snapped the timing chain, you may have luck getting Yamaha to fix it, even out of warranty, but it will probably be a fight and 2-6 months without the boat based on the stories I have heard here.

Water submerged and then bottom end let go and blew everyThing completely destroyed .. ok well could I put the non supercharged engine in my model , and will it plug right in ? Or

 

[SamCF]

No. Don't do the non supercharged. The ECU in your boat won't work, and the engine internals won't work if you put the supercharger on it.

 

[Keeway]

If i swapped the ecu , and left it non supercharged would this work because getting the supercharged engine seems very few and far between

I'm speculating here, but I don't think the 1.8 Non-supercharged will have the power to spin the 160mm pump and aggressively pitched impeller that is found in the 195 boats. I suppose you could get the impeller repitched to "standard" 1.8 specs, but I don't think there is any data or experience on how that will perform.

 

[Keeway]

The ideal thing would be to get a supercharged engine but I can’t find one anywhere .... any ideas ?

 

[2kwik4u]

No idea where to find one.

If the block isn't destroyed, then I don't think there is anything magical about the Yamaha internal components. I would be curious if your local perfomance machine shop could simply remachine and rebuild your existing block. Pistons/Rods can easily be ordered to spec, and any machine shop should be able to measure whats in there and duplicate it. If cams/valves/chain are destroyed that is a taller order, but not impossible. Might be worth asking around to see if there is a local speed shop that does rebuilds that might be able to help.

Likewise, you might be able to get a 1.8L NA motor, and have the bottom end rebuilt to handle boost. Stronger crank/rods/pistons to hold the added pressure. No idea if the cam grinds between the two are the same though.

Lots of work to go this direction, but still might be faster than locating a supercharged engine otherwise.

Have you called Yamaha directly to ask about a replacement? That has to be possible, but probably costly.

 

[Keeway]

Yes I called it was ridiculous like 12,000 k and the engine is toast machine shops could not rebuild it destroyed everything multiple things let go ...

Yikes, sounds pretty rough. Both in terms of damage and cost. Insurance helping at all?

At this point I would be asking a machine shop if they thought they could rebuild the bottom end of the motor for me to handle the boost. New pistons/rods/crank in a standard 1.8L motor might work. Assuming the cams are the same (can do some part number cross checking to see), and you match the compression between the stock and rebuilt unit, you should be ok from that aspect.

Would also want to check to see if it would physically fit and bolt up. Motor mounts, sensor locations/mounts, crank to impeller shaft, etc.

Tough spot for certain.

What about buying a crashed ski with the right engine? junk the ski hull, and transplant the engine?

Who's the company that sells rebuilt MR-1's, wonder if they could help?

 

[Keeway]

I was wondering same thing about doing the wrecked ski

 

[Beachbummer]

Ski with matching engine came to mind too. Best of luck!

 

[robert843]

I would just file the insurance claim and let them fix it with a new motor or keep checking copart till a wrecked ski shows up.

I wonder what the no core charge would be.

 

[SamCF]

I wonder what the no core charge would be.

Yeah. It's probably around $1500

 

[djetok]

That's still a hell a lot cheaper than he had priced already.

 

[SamCF]

I would file an insurance claim if the damage was caused by sinking the boat.

 

[gmtech16450yz]

Sell it as-is. Vdubtech would probably buy it for $40k sight unseen.


lol.
