The Propeller pushes the boat, the impeller is the raw water pickup that supplies the engine's circulation pump with water.

You folks are speaking of the impeller that propels the boat, not the impeller in the water pump, correct? I guess I need to get an impeller pull huh...Leave a comment:

Sounds like the over heating is due to a bad impeller. If you pull it out and find the impeller is toast, inspect the housing real close for scaring and blueing. A bad housing will lead to repeated impeller failure if not replaced. I hope the engine noise you heard was just spark knock from the excessive temp, 250 is pretty warm for and engine with no water in it.Leave a comment:

Help Please! Overheating issue..
So I took my boat (2000 2100V) out last weekend, and everything ran fine and no problems. I've not hit anything in the water or anything that I know of. Took the boat out yesterday, and noticed a smell at low speed as I was pulling away from the ramp. Smelled like a hot engine, if you know what I mean. Didn't smell gas, or oil, and saw no smoke. The temp. gauge showed real hot, 3/4 of the way along the guage, I believe 250? So I got it back to the dock, and let it sit for 15 minutes. Turned the key to see the temp, showed 1/2 way (175 deg), tried to turn it over, but it made a real loud clunking noise, which made me not want to even try turning it over again. Any ideas? I looked at the prop, didn't notice anything seriously wrong, but if you have any inklings, don't rule it out. From what my prelim research has shown, its either an impeller gone bad, or the water pump maybe. I haven't changed either, and don't know how long it has been since either has been changed. The engine is a Mercruiser 350Mag MPI. Oil dipstick had clean oil on it. Please help fellas, not many weeks left in the season. Anybody around here in OKC or Norman want to help with the install, if it's not too tough? Usual install help necessities will be present, food, drinks, you know
