Jmryan034 0 Report post Posted May 23, 2020 My boat is kept on a lift and I’m wondering if I can run the AC while the boat is on the lift. When I turn the AC on I get an error message of HPF. Share this post Link to post Share on other sites
JimE 0 Report post Posted May 28, 2020 AC generally requires the boat to be in the water to operate. The AC uses the water as a cooling medium. While there may be ACs that don't require this I believe most do. One other thing, ACs tend to require significant voltage so if you aren't plugged into shorepower you need to run the generator...which means you need to be int he water as the generator uses water for cooling as well just like the engines.
