They are under the vent baffles on the starboard side
I haven't figured out how to change them as you can see them but can't seem to get to them.
Terrible placement - mine have never worked - easy to be soaked with water.
You can see them from inside if you get on the starboard side of the starboard engine - like you do when you change the filter.

Mine are also under the forward vent grill on the starboard side. If you remove the forward grill you can see both of them, and how they are mounted. They are accessible from beside the starboard engine, mine has a gap on the floor under the wet bar, it doesn't go right to the hull side. It would be a job to replace them though, I'd recommend removing the grill.

Ok I guess I'll take the grill off next Saturday. I'm guessing mine are froze they don't make a sound. I'll try to get a look by taking off the grill first I hope I don't have to get between the engine and the bulkhead. Thanks for responding

Make sure they are getting power, not just a bad connection
