Motor running a little hot - 07/25/16 09:27 PM
I just replaced my impeller and thermostats back in April and all was well till I just took it out last week and noticed it was running a little hot. It's a '96 Merc 150 EFI. It seems to be pumping good. Could this be caused by the high lake water temps? It runs a little hotter at WOT than at idle, but either way the gauge reads a little over half way. I've ordered a poppet valve and am going to replace that too just in case, but otherwise I don't know what else it could be. Any ideas?
