I have Volvo MD7A, 13 hp two cylinder unit with salt water cooling.

Runs perfectly with one exception, it occasionally overheats and I can't
figure out what the heck is going on.

Any clues?


My Yanmar started overheating (according to the gauge anyway) and after
stripping it all down, I finally found a tiny hole in the raw water
jacket into the exhaust manifold.

Does your fresh water level go down when it overheats?
