Ok so here is what is going on. Motor ran flawless all last year, first trip this year on the dock to launch it has a bad impeller housing had a spare and drop it in. Didn't notice in major issues with the old impeller. Out on the lake that same engine is over heating at idle but makes more psi than the other engine. Get back home and flush the system thinking maybe we missed something etc. Run it on the hose and it does not get warm. This last weekend it is still overheating on the lake...
If I bump the RPM's up to about 1400 it holds and sometimes goes back down. Once I get on plane it instantly drops down to normal operating temp. Water pressure varies but under power it seems to be making a little more pressure than the other engine and it has always run about 8 degrees hotter also.
This is one of those issues that you just start guessing which is really annoying...Any ideas? Thermostat maybe?
