Hi,
I have a stainless steel cavitating prop on my 19ft bowrider. The prop has holes ahead of each of the three blades to allow exhaust gas to escape the hub onto the blade surface where I am told it lubricates the blade allowing it to cavitate while the engine spins up into its power band giving a skier a better start.
The engine hits is max RPM when the boat is lightly loaded and gets close enough with an increased load, hole shot is good and top speed is where it should be, however, on the few occasions that I used the boat offshore in a swell, the lack of grip in the swell has been really apparent, I can't see the grip issue being any different when towing.a skier, so is it a gimmick, could I simply get a prop shop to weld the holes closed or would I loose something by doing so ?
Thanks
Duane
