Pretty much the same as snowmobile engines. Some even put a Sea-Doo engine in their sleds.

For "reliable power", change the to aftermarket reed valves and exhaust. Can pick up an easy 10-14 hp. spending about $500.

Next, high compression heads. This is tricky on a snowmobile as your compression varies with altitude and temp. - both can vary a lot. On the water, it should be less of an issue.

Just like the 911, too much compression = detonation. Then, the long paddle back....

After that, find a shop that specializes in these for big bore kits, porting, etc....
