Default RE: Buggy engine in boat?

Most of the current .12 to .30ci boat engines are buggy engines. They provide a water head and rotory carb but the
internal specs and sleeve timings are still car/ buggy. Novarossi and they're Top line and RB are about the only ones
that are helping out with useable timings and button volumes that will work in a boat application.

Car & buggy engine application to a boat will require internal engine mods that I mentioned to make them scream
like your mom seeing a mouse. The engines for car/buggy have cooling issues for obvious reasons and they're torque
load is different.

Sleeve timings in a car/buggy engine are usually low and button "bubble" volume is usually too high, along with crank
rotor timings can be anywhere.

Unless these areas are addressed, getting another converted buggy engine could put you back to square one.
The most unpopular, gutless engine can be transformed into a real killer with mods to the areas listed in this post.
Its actually easier to do the engine mods than to, get the right pipe to the right length, right prop, boat trimmed out
correctly and diagnose what the engine / set-up needs to make it better.
