"I have owned this boat for ye
"I have owned this boat for years and tried all things possible to get it to not overheat over 3100 rpm's it's far better today after all that has been done but still after a while at 3500 it will start to overheat (both alarm and temp proves it). Just ex from my long list is: Cleaned heat exchanger, cleaned oil exchanger, check all connections from water up to pump (incl stern drive and connections), rebuilt raw water pump, checked internal water pump, changed thermostats, checked all tubing for internal obstructions, cleaned exhaust elbow. Please is there anything I have missed I think I have tried it all...Are there anyway to check that I get enough water through raw water system like measure rpm with liters going out..or..? Please this is driving me cracy I need moore sugestions.."
