[C320-list] Bilge blower

[Joe Luciano]

Agree with Jack.  I never use mine either with a Diesel engine.  Just isn’t necessary unless you like extra noise.  Different story altogether with a gasoline engine.  I’ve seen a gasoline power boat blow up at the dock due to a buildup of fumes in the bilge.
