I just boat a 16' Aluminum boat with a 1988 Yamaha Pro 50 outboard. The motor starts well. Idles beautifully, and runs great at higher speeds. But there is a range of throttle in between where it seems to run rough, and shake. Like it is only running on two of the three cylinders (I don't think that is the case, but it is the best way to describe it)
Does anyone else have this problem?
One thought I had is that maybe someone changed the prop on it, and I'm in some weird "speed band".. Thoughts?
