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.
