My boat overheated on Friday while heading back from the channel and per the temp gauge I was climbing over 200 and smoking.
I got parts and replaced the thermostat, impeller, temperature sending unit.
The old impeller had all the pieces still attached.
I inspected the thermostat housing and no blockages.
I did find the source of the smoking issue and my brand new alternator was getting up to 400 degrees and started smoking. So I’ll swap that out.
Manifold, risers, temp housing reading 135 on the gun.
Exhaust water coming out around 120.
Maybe bad temperature gauge. I could throw another one on to rule that out.
No milky oil or water under the oil cap so head gaskets should be ok.
Any suggestions?
