A Volvo Penta 3.0GLP-D heats to 100 ?C when it runs above 3.300 rpm.

It is Ok under it but it heats afterwardsif a rev down the temp drops to 80 - 90 ? C.

I had a broken impeller that I changed and it pumps water OK the exhaust manifold is not hot I dont know if bits and pieces of the old impeller are inside or the thermostat is wrong.


The serial number is

Time to pull the thermostat housing and check it out. May even be a faulty tstat.
Put it in some hot water and see what temp it opens at.
