CONTINUOUSWAVE

I have a pair of 2018 E-TEC G2 200 H.O. engines.

The port engine always runs about 20 to 30-degrees-F hotter than the starboard, at my normal cruise of 3100 to 3200 rpm.

Sometimes, the [port] engine will hold steady at 160-161 for a long time. Sometimes, it blows right past 160 and goes up to the high 170's, then stays steady there for a long time.

Sometimes I get a high temp warning after running around 160-degrees for a long time.

Sometimes I get a high temp warning after running in the high 170'-degree range for a while.

Today, I got a couple of them that happened after coming off plane, and idling for a minute or two, and the displayed temp was definitely around 140-degrees


Q1. what SHOULD the temp be when running at 3100 to 3200-RPM?
Q2. do the symptoms I've reported seem like a sticky thermostat?
Q3. Why would there be a high temp warning when one does not seem appropriate?

You should move your inquiry to the ETECOWNERSGROUP website. They have organized their forum by specific engine models.

See: https://www.etecownersgroup.com/?forum=377900

Diagnosis of engine cooling system problems for E-TEC G2 engines is well outside the the normal range of discussion here.

Thank you, I'll do that. Sorry, I misinterpreted the name of this forum.
