I have a 3.7L 224cid Mercruiser with a alpha one drive. The boat is 22ft and about 3600lbs. I am running at 4600 RPM at WOT, with a 14.5x20 4 blade prop. The engine is running great holding proper oil pressure, temp and holding RPM steady. I can come up another 200 RPM still and be with in proper range but would like some input (any input) on how to pick up some speed. I read several places that if the transducer for the depth find is to close to the drive in will increase cavatation, do you think moving out to the side would help. I am currently topping at 33-34mph according to GPS. Thanks
