I did notice the temperature ran at 135 when at idle, at 140~145 at
cruise
and at 160~165 at WOT, then back down immediately to a lower
temperature
when at cruise or idle.

I plan to keep the 140 in the rest of the season.



Is that engine raw water cooled or does it have a heat exchanger and closed
loop cooling?
