Answer 1

I've got a '20 Larson with a 350merc. On a choppy Lake Erie, at about 3200 rpm (about 40 mph), I get about 2.5 to 3 miles to a gallon, if i'm lucky.  What you have to remember about boats is they are under strain constantly.....a boat NEVER coasts down a hill. It's always fighting to push water out of the way and therefor, gets horrible fuel economy.
