Hi: We have a 26' 1979 slickcraft (AMF) cabin cruiser with a new 454 raw-water-cooled engine. The boat runs great. However, we seem to be using way too much fuel (gas). A trip from Redondo Beach to Catalina Island is using up over 80 gallons, and that just doesn't seem right at all - it's only 26 miles across the sea! We trim it and have a clean bottom. Further, the engine runs perfect with no lugging or black smoke. We are at a loss - your comments are appreciated.
