I have a 1981 Litton Trawler. Brand new to boating. Only had the boat two months and been a great rollercoaster but I DONT DO COLD. I have a Marine Air System Model C16H. I noticed a few days ago that the overboard discharge was getting weaker and not as noisy. It finally stopped flowing ang as expected the heat did too. I troubleshot the pick up pump to be good, no known blockage in the line. the problem is that the coils are freezing, not allowing water to flow thus not making heat?? I thawed the unit with a space heater and ran it with some success. I was able to achieve a 90deg air output while supplying 90 deg heat directly accross the coils....defeats the purpose. The AC pump is working but still have not got it to discharge overboard the way it used to. If I take the space heater off the unit it drops almost instantly and just freezes solid? The outdoor temp is 17-30 and the water is about 50. Please help I see the $$$ flying away by running space heaters.
