Bilge fan

The rest of the modifications.


This fan is located at the end of the flexduct that feeds the bilge blower. It's purpose is to run continuously and silently, always moving air out of the engine compartment.



It's constructed with a 3"-to-4" PVC pluming adapter and a 12V computer fan siliconed into place. It's a square fan, with it's corners rounded off using a belt sander.
