The boat is a 21 foot Champion. With the 4 blade 21 pitch, i was getting about 3,000rpm. I switched to the 5 blade 18 pitch and I came up to about 3,400 rpm. Both props are stainless, if that matters. I was told that I should be closer to 4-5,000 rpm on that motor. I wonder if there is something else not right with it. Maybe in the fuel system or electronics??
