I have a Marine Air 7000 BTU reverse cycle AC unit, with the March PML500L raw water pump. It has performed great in the two years that I've owned the boat, except for the last two times I ran it. Both times the pump refused to prime. Each time I've pulled the output hose off the pump, which broke the air lock, and it's worked great. I should mention that I trailer the boat, hence the air...
So my question is, should I suspect that the pump is getting weak, and if so can it be rebuilt or does it need to be replaced? Clearly I could close the seacock before pulling it out of the water, but I never needed to do this before and it always worked fine.
Thanks for your advice.
