Hi Art,
Sorry to jump in here - as I am not a 330/350 owner, but I think our boats have similar hulls - at least the '08 350's do.
I just replaced my vent fan motor - it has a "Y" duct adapter on it and duct work that leads to the head and galley. There are 3 way switches in the galley and head to turn the motor ON and OFF. The motor is a Mayfair 5412, flange mount, and it is mounted against the hull on the port side mid-ship. On my boat, I have two "clamshells" on the hull there - the aft one is the central vac vent, the forward one is the vent fan "vent" (you can look at my sig picture and see the two clam shells just above the Sea Ray emblem). The vent fan motor is accessed via the port side cabinet at the foot of the couch/bed in the mid (aft) cabin, there is a window in the cabinet that allows viewing of the battery charger. If you unscrew the cabinet shelving and back wall, you can see the vent fan motor about 3' forward and 3' above the battery charger. Wasn't fun for an old guy to change, but with Aleve pre-treatment and tequila post-treatment, I survivded!!!
Sounds like you may have a switch problem rather than a fan motor problem...
Thanks Carter - That is great detail, and I think you are right: if only 1 motor, and the motor is working, it probably is a switch problem -
