It's probably time to replace the original Marine Air Systems 10k AC unit on my 2007 330 Express. Although I have not had any issues with it, and it still runs ok, the pan is all rusted out, the unit itself is deteriorating, and it's starting to smell a little.
I've just started looking at replacement units, specifically the Dometic Envirocomfort and the CTM units, however it looks like they may need to be modified to accommodate the return.
I'm hoping someone has had a good experience with a retro fit unit that could share their opinions and offer some insight on the project. I was also thinking about a way to send one line up to the helm for a little AC, but that may require an entirely separate unit. I've attached a few photos of my current unit for reference. I appreciate the help!
