Yes yes yes...I know, refrigeration is often overlooked until its breaks down.
Well we finally had the boat out today for the first time this season...loooong overdue...anyway, the "cold" plate wasn't cold at all, in fact it got hot????
It's a water cooled engine driven system and according to the PO, he and his "engineer" brother designed it

. I guess I just ignored that when he told me. So I cant find any thing to identify what was used to build it.
I am thinking it has to do with a hose/leak in the cooling system as there was some water in the bilge thats not usually there. (at the time I thought the unusual water was the new
shaft seal needing adjustment) Perhaps it didn't get a good winterizing and caused something to fail????
It has always worked well, with-in an hour it was frozen solid, and just needed about 30 minutes a day to recharge, even in the summer.
Thoughts please.
I tried google and a search but didn't come up with much info.
