Hi Can someone tell me where the bilge blower is located on a 1977 45' commander with fly bridge.
FWIW on my 1972 ‘41 it’s located in the engine room on the starboard side just under the salon floor. Best bet, just follow the “dryer” hose from the bilge and you’ll run into it.
I can't imagine if it's working you couldn't hear it in the bilge. If it isn't working look on the hull mid to aft of the engines. There should be ducting into the fan inlet.
With the engines off I can hear mine loud and clear!
Not working it is on a friends boat on mine it is behind the sofa in the wall behind a teak panel.
A boat that size should have at least two.On my 41' there is one behind the paneled wall on port as you come down the stairs and a matching one on the starboard side same place. neither of mine is in the engine room, they are halfway up the salon wall and have dryer hose in from the bilge and then out to the duct exit on the toe rail
