fuel capacity
 

Does anyone know if my just acquired 1985 20ft seacraft MA has a 47 gallon or 70 gallon fuel tank? Previous owner said 70 but I question his.....memory.

They came with 47 or a 70 gallon option. Open it up to see the tag or drain it and fill it. I'd take his word for it. Of course you should determine this independently if you're planning a run to Cuba or the Bahamas ;).

The 70 gallon tanks were common in the Seacraft Industries 20s (early '80s) and, I believe, the Trackers (late '80s), so that's probably what you've got. That's what I've got in my '83.

Thanks for the response! From what I've found, it appears that the standard tank was a 47 gallon and there was an option for a 70. Everything in original--kept in a garage for a long time. Had a few boat guys around here check it out and they sure do like it! Getting it back in the water today!

My 85sf 20 came with a 70. I replaced it with a 50 pushed forward

Measure it in feet or inches to get its cubic volume; L x W x H. Divide your volume by the cubic volume of a gallon and then you'll know. Cubic volume of a gallon is 7.48 gallons/ cubic foot.

1 gallon = 231 cubic inches.

1728 cubic inches/ cubic foot.

Good luck!
