I'm using a topside tank. There's not much room below deck, its mostly full of flotation foam and the way the stringers are situated with one right down the middle it would make balance difficult. A 14 gallon right across the transom would be best.
Lots of good points posted here. I ran a 19’ aluminum high-bow CC skiff five days a week on a 22 mile round trip with a 90 hp Honda four stroke for several years. I was really glad the boat had a 15 gallon under-deck tank, with access ports through the deck for fitting maintenance. The tank was athwartships just forward of the CC, which on that boat worked well for trim. The fuel fill pipe was on the stb gunwale, and had a little catchment around it to contain any small spill during fill-ups.Any recommendations as to what would be a good size gas tank? Also, if space wise it worked better to have two tanks, one on each side, is there a way to rig it so it pulled from both tanks equally?
Deal! What kind of beer do you like? Have to at least give you six pack.
