Help, I own a 1984 Catalina 38 #274 with a Universal M-30 5425 engine. Months ago we overheated, the shop I was in replaced the raw water pump but the leak continued. Further research showed the leak was coolant. So long story short we have replaced the fresh water pump, thermostat, cleaned and pressure tested the heat exchanger ( radiator shop), pulled the front plate from the engine and replaced all gaskets and O rings but still have a coolant leak from the area near the alternator bracket. We have checked all cooling system hoses and have found nothing. Any help or suggestions would be appreciated.
