I've just crossed 5 years and 500 hours on my Yanmar 3JH5E. I'm pretty sure I'm dealing with the original belt and original impeller. I've not had any significant issues with engine performance but I have noted that when running WOT, the temperature does seem to be about 10-20 degrees hotter on the temperature gauge than it was originally.
I will be flushing and replacing the coolant this year (I think its been 3 seasons since I last did that).
I'm trying to determine whether this belt should be replaced. It looks almost brand new but I was just reading that some of the newer belts don't show the wear the way the older belts showed.
Any opinions?
