Re: fuel range in a 20
I can get over 3.5 mpg cruising an '02 carbed Merc 150 at 4000 on a 20' Grady White CC. My boat is a bit heavier than your 20' SeaCraft so on calm water, I would expect every bit of 3.75 mpg from your setup.
These Merc. are very fuel efficient. [img]/images/graemlins/smile.gif[/img]
