2009 SEA RAY 350/370 RPM & PROP QUESTION
I own a 2009 350 / 370 Sundancer with Bravo 3 Axius stern drives and 496mag engines . When I plane the boat at full throttle the max rpm's I get from each engine is about 3900-4000, the boats max speed is 38-40 MPH . A friend of mine has suggested that I should be getting much higher RPM from my engines, close to 5000 and that I may have propeller issue . The previous owner of this boat informed me that he had the props "cupped" to increase efficiency, I know nothing about this process and what the effects of this prop modification is. Anyone have this boat and have any experience with what the top end speed & rpm should be ?
