Do any of these four strokers come with a non-cavitating reversing prop? The prop in the photo generally has little drive when in reverse because the engine exhaust is fed right into the prop causing it to cavitate. It is possibly even worse when the exhaust exits through a center hub. They go at high speed in reverse, but there is minimal reversing thrust.

For those that need a strong reverse, particularly when entering or exiting their slip in a blow, the Yamaha has an anti-cavitating prop that works spectacularly. It will stop an Ariel almost instantaneously. Tremendous reverse power. Enter the slip at a couple miles an hour with full steerage, throw it into reverse and voila - stopped dead.

Does anyone know if these are available with any other motor than a Yamaha? Particularly with the four stroke?
