The reasons for adding cabin fans are self evident. I got the Hella Marine Jet Single Speed fans, they don’t move a ton of air, but it’s enough to create a pleasant feeling draft and they don’t use much power so they can be left on all day without any concern about the power drain. Installation was fairly simple, although running the wires was a little tricky. I also added an additional 5A breaker to the panel for the fans.
I didn’t like the way the power cord was routed on the fans, so I drilled an extra hole in the mounting base to allow the power to go through the base and the hole be concealed by the base as well.
After a number of overnight trips this season, this simple upgrade was well apprecieated!
