Performance mods 12 sx240

[Omg8]

Now I know these wont be race boats, but I have a race car and everything can be a little faster, been looking to see what parts are available out there and dont really see much of anything.
Any intakes?
Exhaust parts?
Tuning?
Impeller?
Intake grates?

Ls swap it. Nothing else will make a difference.

Lol funny you say that. I have a 1500hp ls car.

 

[Omg8]

Anyone try the magnum tuner deal?

 

[Jgorm]

Twin 1500hp ls, Berkeley jets, jetorator, etc.v who said these can't push 90mph!

I would start with this thread. The mods were done to a single engine, supercharged boat, but these are the best results I can recall seeing.

If you're looking to increase top speed, realize that you only have one gear and an rpm redline.... Unless you significantly change the pitch of the impeller, you can only affect the acceleration but not the top speed.

You can use a map tuner and ribbon delete to get a little more out of it but that probably just a 3-5 mph improvement.
