In Feb. I bought a 97 chris craft with an over heat problem. I have changed the impeller and thermostat, I have also resealed the lower gear case. With the thermostat removed the motor stays cool at idle, but heats up immediately under load. With the thermostat installed the boat heats up instantly. When running with the muffs on the motor stays cool. The boat has only been in fresh water. The previous owner had an old impeller that he replaced that had no fins left.
What would be the next step in detrmining the problem? Is there an easy way to know if the manifold is blocked? Could it be a blown head gasket?
Thanks for taking the time to read my thread. Any advice would be greatly appreciated.
