2003 Volvo Penta 4.3 has started getting warm. We pulled out the impeller and it looked good. The impeller is only about 6 to 8 months old. Seems to be pumping plenty of water, but the temp is right around 225. Any ideas?

Re: Volvo 4.3 Running Hot

Are the exhaust manifolds and/or risers getting plugged up?
