Seafari 20 I/O fuel tank pictures and measurements

[Bikecop1]

Any one got any pictures and measurements of the fuel tank in a 20 Seafari I/O. Mine was removed and has nothing. Thanks.

The measurement of my 1979 20'cc i/o tank is 5'L x 2'W x8"T

Found these pics from my 1976 Seafari 20,the Blank Canvas. Still have tank for measurements, I believe to be 40 gallons as does my 1977. Blank Canvas came with everything but fuel hatch cover, outboard and drive. Let me know if you want measurements.

Does the fuel filler come off the top or the side? Thanks.

Yes. Measurements please.

Thinking I'm going to have to measure and have custom built. RDS said they didnt make a 29 or 38 gallon tank for the seacrafts. db3155, your measurements equal out to a 49 gallon tank which is what the outboards were supposed to have. The I/O's show a 38 gallon tank in the brochure, however in the 69 brochure on the Moesley sight lists a capacity of 29 gallons, which is what I believe I have.

This is a photo of an attempt at removing a fuel tank from a 1976 Seafari 20. It was an I/O model, and the tank was stuffed under 3” floor that ran across tank hold to rear, where dog house hinges were located. Hind sight I should have cut this section of floor out, but pryed from front and slid out forward. It was a bitch. Could not stuff one more gallon of fuel in this spot. Rear of tank must have been pretty damn close to the engines flywheel. Measurements coming BikeCop.

If you are going to do the measurement route, I strongly suggest you make a mockup of your tank out of scrap plywood and then test fit it into the space. It is a pain in the butt, but better than wasting money on a new tank and finding it would not fit, or needing 20 hours of glass work to modify the opening and deck. Here are some photos of my mockup to give you the idea. I modified the measurements twice - once from my test fit, and then again when Bushwacker gave me the measurements of his tank. The first time I measured it was too big to fit, and then with Bushwacker's measurements I added back some dimensions that I had reduced, increasing the capacity by a few gallons. Make sure your mockup includes the vent and fill elbows.

Jesus, where have you been? Got me beat. What’s the gallon total? Where did you have it built? Help a guy out? Haha. Nice work. Built in Bayville/Speedy Tanks?

I’m friggin sitting here eating not so good South Carolina Chinese! Going to get the rectangular measurements. You called me out SailorChlud... Haha

OK, damn tank may still be good??? Needs pressure testing and will probably stay with The Blank Canvas.

Measurements are 49” (about an inch long) X 16” wide X 8” high. Fill, vent, sending unit and pickup mounted on top, and I assume aft (all located at one end) but sending unit.
