- 2001 260 HP V8 Mercruiser
Hello,
I recently purchased a Sea Ray with a 2001 Mercruiser 5.7/V8 Alpha.
The engine runs too hot. Even at RPMs as low as 1,500, the gauge will creep all the way up to the top H.
Risers not too hot to keep hand on. Manifolds VERY hot. Too hot to touch.
The water pump has been replaced last season but the circulator has not. Also, boats thermostat has been removed at some point.
We've cleaned out the manifolds to the best of our ability, but there's certainly some crap in there. Looks like rust.
Any advice on what the issue might be?
