Hi,
I have 5.0GL PWTR Volvo Penta SX Drive, that has an overheating issue, that I cannot figure out. Here is what is going on:
First strated overheating in Idle, and would cool while driving. It was an air leak, the boat place fixed it and also said that my upper seal was bad and replaced that as well...$900.00 later I get the boat back and now I am using a 160 degree thermostat that is new, the boat idles at 150 degree but when I am going about 3000 rpm, the temperature continues to rise up to at least 200 degrees, before I stop and let it idle back to normal. If I go full throttle it doesnt get over 180 degrees...I have flushed the system, checked the oil cooler and everything else seems to be working...Has anyone had this issue before? and what would cause this to do this? Could it be the sea pump leak?
