Ran the boat on Saturday, man it was great. The engine owners manual shows the max RPM'S for this motor to be: 4400. I noticed with the addition of the ramp loader and rebuilding the carb , I now have about 5400 RPM'S, I don't recall if it changed with trim up or down. Before the ramp loader,on the 12JE pump, it was about 43-4400 RPM'S max. Is this due to the ramp loader?
