I have not had issues restarting and the engine never seems to get over 173. I have bottom paint and can get it up on plane at 3800 ish RPMs with a little trim I back it down to 3500 RPMs and cruise at 28 ish MPH. The temp gauge seems to sit a little over the 170 mark. I'll be changing the impeller at the end of the season and may swap in a 160 thermostat which I may already have but a new t-stat is cheaper than a new motor. May also try to flush the engine when I pull it this year. I have googled around and I was unable to find a real consensus.
Thanks for the info Jakester. Good luck w/the new stat, hopefully that does the trick. I think I will check & see what mine is also. Couple of quick questions on the performance you described if you don't mind.
- 3500 cruise @ 28 MPH - Full of water & fuel? How many people can you have on at that? Does a few people make a drastic change for you?
- Right now I run 22P props & have changed gear ratio to 2.2 due to higher elev. Going to check out running 24P & see how it works. What pitch do you run? Have you tried any different?
- Have you changed anything with the tabs? Larger, more travel, etc? The factory tabs move relatively little compared to what I'm used to (couple inches at most) & only about 10" wide. Seems like maybe there should be a little more for the size of boat. Have you or do you know of anyone making changes to them?
