While I hate to admit it, many years ago when I first started sailing I changed the engine oil and replaced it with non-diesel rated engine oil. After that if I ran the engine hard ( usually beating into bad weather) the engine would overheat. After realizing what I had done and replaced the oil with the proper rated oil I never had another overheated alarm.

Sorry, to be precise it has not happened again, but I have watched the temp
gauge like a hawk and not run the engine wide open for a long time. I checked
the entire cooling system and it was OK. BTW, there was a recall on some of the
heat exchangers that were inadequate in the first few 3YM-30's installed but
mine was not in the recall.

Kurt,
You say that your engine does not overheat 'as easily'. It should never
overheat, so you may want to check everything again. One thing to check is
the heat exchanger--you may have limited water flow due to debris there, but
it sounds like checking the entire fresh and raw water cooling system is in
order. Checking the thermostat is also easily done...Good luck...

Susan,
I have a Yanmar 3YM-30, year 2005. The first year all was fine. The second
year the engine overheated running at wide open throttle after 15 minutes.
It usually runs a temp of 180 degrees, but overheats when it hits 220
degrees. I was told I did not have to change antifreeze every year
initially, but Yanmar told me I have to change it yearly even if it is
Dexcool. Since I have changed the antifreeze it does not overheat as
easily.
