I have a Marine Air 12 K BTU unit and not sure of the age. I used AC in the summer and heat later in the fall last year. I wasn't sure if the reversing valve was working at first when I started using the heat, but eventually it worked fine last fall. I read that reversing valve may tend to stick.
Saturday, we were in the low 50's so I turned on the heat. I made sure the valve at the thru hull was open. Stupidly, I didn't verify that the water was pumping and I left the boat for about an hour. When I came back, no heat was generated and it was obvious that the water wasn't pumping. The pump was still running and very hot to the touch. I shut down and put it out of my mind for the time being.
I painted the surface of the strainer with bottom paint, but I was sure not to clog the openings, at least I think they were not affected! Any thoughts on where to go from here? I'll remove the hose to make sure water flow in the intake is good. I'm concerned that I ruined the pump. Can the pump be replaced without replacing the entire unit? Any thoughts welcome!
