Re: Yanmar 4jh3-hte overheat

after experience in dirty harbors with running the aircon and full sea water filter, overheating of engine friend ones SM I decide to install the attached instrument. It get installed after water injection in the exhaust and acts much faster then the engine temp control. The temperature of the exhaust increasing much faster then the engine himself. With this you can control the sea water filter and the impeller!!!

I'll check the transmission cooler, good advice.  That wasn't the primary cause though, as I noted, the engine seawater pump had shed all of its vanes.
