Motor is an 09 etec 200 HO
model: e200HSLSEA
SN: 05236046
So I've been having this issue with my etc over heating at idle. I replaced the water pump but that did not do it. I replaced the t-stats and problem was gone. No more hot alarm. Tonight I wa ps idling into the marina launch and the hot alarm went off.
Should do I replace the t-stats again? The reason. I ask is that this motor was running fine and idling through the no wake zones and idling while I graph just fine until tonight. Maybe the stats went bad again?
I have noticed that my water pressure gauge gets no reading until the motor has been running for 15-20 seconds.
Before i I replace them t-stats the first time I planned to ra place the pressure release valve if they did not solve the problem.
Anyway now im a bit confused. Anyone have any suggestions?
