[QUOTE="PSG-1, post: 320077, member: 6937"] YIKES! Yep, that would definitely cause cavitation. I think you will see a noticeable difference when you install that new, undamaged prop. Note how the hub of the stock prop has that extension with the wrench flats. Those can cause cavitation. The newer impellers have recessed splines, and use a specialized tool to install with (they should have sent you one) and it's capped with a rubber or aluminum grommet. This gives the water a smoother path to flow across. Very nice! Did you install any sound proof foam in the cowling? If not, you should consider doing that. Mcmaster-Carr has some that reduces sound by up to 80% and it is fire retardant. Installing the egg crate acoustic foam will dramatically reduce engine noise, making your ride more quiet. [/QUOTE]
