I am looking to install a marine ac unit on a 2000 238 vista for better confort. Has anyone done this on this boat that shed some light as to where yo place the ac unit. I will be doing the install in the near future but before i go ahead and start tearing things apart i would like to get my bearings straight. The unit that i am looking to purchase sould be between 4500 to 6000 btu. From what i read its more than enough for that cabin.
