Hi All,
I have an 86 E35-3 with a newer Universal 30hp/4cyl engine & a MaxProp. I'm trying to decide if I have the correct pitch on my prop. Does anyone know the correct hull speed for these boats? Right now I'm running at 6.2 knots at 2700 rpm. This rpm is just above the recommended cruising rpm. They recommend 2200 to 2600. I'd like to increase the pitch & drop rpm to 2200-2300. The engine noise and vibration are excessive at 2700 and smooth & quiet at 2300. I am of course concerned with overloading the engine & shortening it's lifespan.
Would appreciate any comments of those who have addressed this issue.
Many thanks,
Steve Gabbott
