Thanks for the feedback guys. Based on what I've read here and elsewhere, I figured I was close given the RPM range and WOT RPM I've gotten. Maybe I'll try a 4 blade with similar characteristics. I wish there was a prop shop around that I could borrow different props and try them out, instead of having to buy them!
I don't know if the tach is accurate or not. Its a new analog unit, but I don't know if its possible to calibrate it. How do I check the actual RPM without the tach? Is there a way to put a timing light on it? Maybe I should read more in my manual...
I think the motor height is pretty good. I just guessed when I mounted it (based on info I'd gotten here, thanks!) after raising the transom to 25". Running on full plane the AV plate is just above the water coming off the transom.
I know the boat is heavy too, and it sounds like this has a lot to do with my symptoms. Replacing the cockpit sole would help a lot as I know its wet. But this is more work than I want to do right now. The boat has the larger 70 gal fuel tank as well, and sometimes we pack it totally full. If it turns out I'm going to keep the boat another few years, the cockpit sole is a repair I would like to make, and would probably make a big difference in performance. I would move the fuel tank forward as much as possible at the same time, maybe even install a smaller tank.
Anyway thanks for the help guys. Great forum!
