Got a good deal on a 1985 bayliner carpi 19". $2000 cash. I will attach pics of boat and engine. I believe it is a volvo aq125, correct me if im wrong. With a volvo 270 outdrive. When i bought the boat i noticed antifreeze leaving from behind the heat exchanger. We couldn't locate the exact place it was coming from. The starts and runs great. so i could not pass up the good deal despite the coolant leak. I was going to try and locate the leak myself but her is my problem. Using earmuffs around the water intake on the drive with a water hose I cant see water coming up through to the heat exchanger with the cap off. At first i thought maybe it had to worm up for the thermostat to open but after it got up to about 190 i didn't want to run it any longer. Am i doing something wrong? How hot should l let the oil temp get with the ear muffs? Could the thermostat be stuck? I don't even know if the lake water side has a thermostat or is just the antifreeze side? Anyway before i locate the leak i at least want to know how the heck to run this thing with a hose. Also i tried filling up a rubber made tote with water and submerged the drive and still no water flow to the motor.
