Evinrude overheating

[Bigsmitty]

1999 115 Evinrude 2 stroke.... when I run her at higher speeds for an extended period of time the overheat alarm comes on and I have shut her down for about 15 minutes to cool down. It seems it only happens when running on real smooth water. Any expert advise? Do you think that it could be the impeller? Or maybe the temperature sending unit? It seems to always piss out a good stream of water. Any advice would be appreciated.

Definitely the impeller, a good tell tale stream doesn't mean much.

Replace it every 2 or 3 years and you will not have any problem, it's a $ 25.00 part, don't risk it.

I wouldn't use your motor until repaired.

Thanks Valv, Its top on my list before I take the boat on the water.

Now that Valv solved your problem you can tell us the real name of your motor. We all know Evinrudes don't break down or cause their owners problems. Good Luck!
