My Volva MD2B
quit on my the other day. It restarted right away but I let it cool for about 30 minutes before really using it again (to get back to dock). The prop was a bit fouled by crusty growth ( could that extra load cause a heating
Now that I've been searching around for typical operating temperatures for this engine
I'm a little bit alarmed because a lot of them see very low in comparison.
I've been running this engine
for a couple of years now and the typical water
temperature on my gauge is around 190F, sometimes going right up to the 212 mark. I recently bought an infrared gauge to see what other parts
of the engine were up to. some parts
around the cyclinder were up to about 220 F, while the thermostat cap rarely goes over 100 F.
Have I been slowing killing my engine with heat ? It's been very rock solid and has been run in this condition for up to 8 hours at a time with no apparent problems.
Any thoughts ?
