I have a 1980, 32' with a 2qm15 and the first year I had it, same thing happened. I spent hours trying to figure out what was wrong, and finally my son in law said lets dive the boat and look at the prop. If someone had told me that "stuff: on the prop could have made that much difference, I never would have believed it. Dan Mc

What prop do you have on there, and is it able to achieve max rpm under load? I can't recall what I have (3 blade but don't know size/pitch) but at 2700rpm I am billowing black smoke and still only doing 5kts. Dirty bottom is going to contribute to this, plus some junk on the prop itself, but I wouldn't have thought it would be *that* big an effect.
