I recently bought a 13' Sport. It is in excellent condition. The problem I find is that the seats have only 8" of clearance underneath them. Neither the battery or gas tank will fit under the seat. I would like to find some way to do this without making a major modification. I do not want to make any permanent changes. As it stands right now, I cannot use any of the space behind the rear bench. Does anybody have any suggestions?

I found the same problem on my 13 and latter on my 15. My solution was to build a closed section behind the rear seat on the 13 it went accross the entire rear and opened from front to rear. (a good latch is necessary) The 15 I used two hatches opening from the sides to the center. Tried it on the 13 origionally but the hatches were too small. Used T-111 plywood painted with the "right" side down. Put marine carpet on it, and it makes a great casting platform. Joe

butler, getthe slim tank that fits under the rear bench. Pate or somebody makes one. I had it in my 15 and it was red glass and about 15 gals. The battery is best fitted under the steering wheel. You can't get you legs in there so why not. The reason I moved it there was everytime it rained to much it got submerged in the back. In FL it can dump enough rain in an hour or 2 to fill that boat to the splashwell. You forget to pull the plug and ZZZZAP!

same thing goes for the tank, I like the fact that the 6 gals will float. the 15 will not if stuffed under the seat, etc.

I don't think that TEMPO makes a tank with clearance low enough to fit under the seat. I bought their lowest one, dragged it home and tried it: won't fit.

MOELLER has a tank that is listed as being about 1.5 inches lower. That might be the one to get. Some catalogues have the Moeller brand of plastic fuel tanks. The marine stores all seem to have Tempo.

On my 15' Sport, the previous owner added small blocks between the side risers and the rear seat to allow more clearance between the floor and the bottom of the seat. My battery, and two 6 gallon Tempo gas tanks quietly live under the seat with a fuel selector valve switching between tanks. None of this is entirely "permanent", other than the length of the wires that attach everything to the battery. If I wanted to revert to stock, I take off 6 or 8 screws that hold the seat to the risers, remove the blocks, screw the seat to the risers with shorter screws.

I have seen the slim red plastic tanks designed to fit under the thwart of a stock 13. I'll look around for the source. I always wanted one because the 6-gal Tempos leaked like crazy and cluttered up the back of the boat.

Real pain if you water ski and such. Back in the days, it was not a fun experience to fall on 2 METAL tanks.

Is this what you're looking for? Think I've got to have one for my 1960 13 sport.

I have a Moeller 12G (from Cabelas for $89.00 + Ship)on my 13'68, under the front seat , I had to cut the seat around the cap and made some brackets to hold it on place ,I don't like that the cap is vented but not screw-vented ( like the Tempo)but has a gauge on it and that's cool,also raised back seat 4" now I got room for the Batt , life jackets and tackle box

Chrisc yes the Tempo 12 gallon model 126 is the correct tank and will fit including cap under a 13 or 15's seat. Overall height with cap is exactly 8". The tanks are 15" deep and are designed to leave 3" exposed from the rear of the seat, in other words the seat doesn't cover the filler cap.

I have a moeller 9 gallon tank positioned fore and aft in my 15, I think the clearance is the same on both. The nine gal is enough for me, If I need more I have an evinrude 6 gal metal aux I can throw in the back.
