Your photo post # 11 shows a Yacht Air, Pompano Beach control panel. I have Yacht Air air conditioning / heating on my boat, two, 1600BTU units, similar panel. They use heat strips for heating. It has been a while since I have used the heat function and I don't remember if the water pump or compressor would run while it was in heat mode. I can give it a try during the week and let you know. Yacht Air seems to have ceased operation a few years ago, a pity because I had called when I bought the boat in 2008 and they were very helpful. I do have an owners manual for the Yacht Air units on my boat when you have time check your units, the green one you pictured, see if they have a Yacht Air Label on them and what model & size. If so I can send you a copy of my manual.

That is incredible news. I just figured boat was like house in that you could have any brand name thermostat and it didn't really affect the system. Clearly not and I can now just ignore that cruisair manual I have. I'm pretty sure I don't have any plates to reference but I should be able to take a thorough look tomorrow. I'm not really sure what strip air is (other than the obvious sounding name) but I'm pretty sure I don't have that. Heat comes out of the vents from the cooling unit just as it would for a reverse cycle system. I am now assuming resistance heat. Thanks for the reply. Really helpful.

Apparently can't even count on being able to do that anymore.

We had new AC/heat pumps installed at home in 2016, and both needed new thermostats. The third semi-annual service call happened last Thursday, and this tech (finally) noticed they had installed an incorrect thermostat on one of the systems; said it wouldn't effectively control that particular heat pump in extra cold or extra hot weather.

New thermostat installed (at least, no charge for that). Now we're back to having two different thermostats, one for each of the two different heat pumps.

Here are a couple more pictures of my system. The compressor units are made by Copeland, they look quite similar to yours, same for the Temp/fan speed controller. I went over to my boat today and ran the heat function it worked fine and no water was circulating through the unit.
Maybe Copeland supplied compressors to Yacht Air and Cruiseair. Maybe you have a Yachtair system but a previous owner had a Cruise air manual on board.
The blue stickers were put on the units when an A/C tech replaced the 22 freon with DuPont MO99 last year.

That does look like them but yours are in much better shape. Mine are missing the cover panels with the nameplates unfortunately. If you have an electronic copy of the manual I would love to have it. If not please don't go to all of the trouble of scanning it. I'm just happy to at least know what I'm dealing with.

Well Christmas miracles sometimes come early. I found the cover plate loose in a corner of the engine room. Looks like the same model as one of yours.

I don't suppose you have found any place that supplies parts? My rear unit burned up the switch plate. Or does Copeland make compatible fan/heat/air switch units?
