Volvo MD11C Overheating
I have a Volvo MD11c that is raw water cooled and is overheating. Last season the temp would climb until it hit the red zone then move back well into the green zone(cooler). I have replaced the pump thermostat. A large volume of water exits the exhaust.
This season the temp climbs up to just near the red zone and stays there.
I think I need to remove the exhaust manifold and boil it out.
Am I on the right track? Also any advise on how best to remove it, any tricks and should I try to clean the water jacket on the block?
BTW: the boat is a Pearson 323
