OBP,
How much fuel do you carry in your 20? That is a pretty good poke to be able to leave Sandwich (I assume the basin) fish the SWC of Stellwaggen, run around the corner and then pound your way home at 12 knots, spending more time going up and down than you were forward from the point.

I've got 76 that is pretty close to yours with a replacement tank. (I still need to post some pictures). Its got the I/O (140, approx '84). Dimensions tell me its approx 30 gallons, not sure how much is usable (that is always a tough one to completely determine). Down in CT now. I'm still trying to get a handle on my fuel consumtion. I'm still a little over wheeled (19x14, should be the 17" stainless, next season) but I cruise 21-23 knots, turning 3300-3400 ( I know its apple to oranges yours to mine). Just wondering if you carry an extra tank or two and transfer once you get there. Engineer things i guess, being overly conservative.
