Kevlar382 is correct on the RPM's and speed as I owned his old 88 311. Another friend of mine with same boat ran 24p hydromotives 4blades. Slower top end speeds but better cruising speed. I still have the 25's Mirage non plus and thinking about selling them as I sold the boat. Keep them as a spares after I re-powered the boat.

Dave, where did the boat end up. I like to keep track of my old ones. If you ever talk to him please give him my number so I can help him out if he has any questions. Did you get a 382? Hope you have a Happy New Year..

Sorry it's been a long time time, but if I remember right my 1988 with 330s ran 66 at 4800 rpm. They both had 1.5 Bravos. If you want to run 4 blades, you might want to try turning them in.
It ran 66 on gps?? That's damn good for 330s...
