Chris268- THANK YOU for those links!! I bought those vents, and ducting from them. I ended up buying a different Y-connector due to space constraints. I appreciate those links, you saved me considerable money!
The A/C is installed
After ALL these years of having a factory installed generator, but no a/c, and complaining about it non-stop as I tripped and struggled lugging around that STUPID over the hatch A/C, I bought that Marinaire 6K btu "micra" unit, along with the install kit from Marinaire, and circulating pump, and it took 2 days after work to install everything. Im going to guess it took us 8-10 hours to install.
Four Winns had pre-installed a water outlet thru-hull out the side of the boat from the factory, and ran a hose to the bilge (with a plug on the end) so that saved us some time. We reused the toilet seacock, as we use freshwater to flush the toilet anyways. Wired it to the panel, bam. The 6K BTU Marinaire is a BEAST. That thing cools and dehumidifies (the thermostat has the humidity % and temp) very nicely. It has a remote control that you can use, with digital readout on the remote. The unit seems very well built.
The A/C installed under the rearmost dinette seat. We lost the storage under it, but trust me, it was WELL worth it. Ran one vent facing rearward into the mid-cabin, and one directable louvered vent out the side, that faces the fridge. That vent cools the front of the boat.
