Hello all, first time posting here. I have a 1978 Sea Ray with a 5.7 alpha one outdrive. The issue I have come across is not being able to keep this boat from overheating on the water. It has been the issue since day one of getting it. I can run the boat on muffs and the temperature stays normal being at idle or bringing the rpms up 2500-3500. The engine never gets lose to running hot. Now I am not 100% sure if I have the thermostat housing that requires check balls, I have the log style exhaust manifolds. I have replaced the impeller and housing, cleaned out the out drive, replaced the hose running from the out drive to the hull, replaced the thermostat, water pump and manifolds and risers. When on the water I removed the plug on the side of the thermostat housing when starting the engine it shot about a 3 ft stream of water out if that info helps at all. I am at a loss at to what else I should look into? Also, I have removed all the cooling hoses and made sure there are no obstructions in them. Thank you for your time and advice, hopefully there is something obvious I have overlooked.
