Yamaha 200 HPDI (2004).
Been having an intermittent problem with overheat alarm on one of my engines. New water pump and t-stats but that did not fix the issue.
After doing some research I expected it may by the poppet valve. So as a test, I started the engine and let it idle in the slip for 20 minutes and never got an alarm.
On some trips I have no problem. Last trip I was wreck hopping covering maybe 5-7 miles at a time. Did not have an alarm until my trip back to the slip from the last wreck only about a 4 mile trip.
Pulling my hair out a bit as to the intermittent nature of the problem.
One thing I should add when flushing from the hose flush on the engine the engine that overheats pees way less than the 'good' engine. This leads me to think there is a restriction somewhere but when running both engines pee the same.
Anyone have any educated guesses as to what could be the problem?
Thanks guys.
