I am sea testing my recently acquired 15 with an OMC 70 and as stated on this forum, the mpg is about 5 and a 6 gallon tank will last about two hours. I have been trying to figure out a way to install a larger tank capacity, and wonder if it would work to raise the front movable seat board and rest it on cleats on the side boards. This might give enough room to install a permanent built in tank? Any ideas appreciated.

I used a 12 gallon Tempo with another 6 gallon Tempo. Both fit on the deck behind the pilot bench seat on my 1977 Sport 15.

Ron, the previous owner of my 1985 15' Sport raised the rear seat about 2" and managed to get two 6gal gas tanks and the battery ALL under the rear seat. I added a 2-way valve to choose which tank I pull from. When it starts sputtering, I reach down and flip the valve to the other tank. Last weekend I ran back to palm beach inlet on that tank that I'd previously run 26.4 miles on, and it did another 3 miles of idle, and 4 miles at 4000rpm before it ran dry. I can E-mail pix if you'd like.

Tempo makes a 14.5 gallon that is 11.5"Hx43"Wx15"D. Published height says 9.5" then fine print says add 2" for fuel cap! West Marine offers them for sale at @$135 At this size, you won't fit the battery under the seat with that tank, I don't think. Specifically says "Fits under Boston Whaler Seats"...

Ron, I have a 9 gal Moeller tank, great size and price is right. Also was at our local K-Mart and noticed a 6 Gal tank sold under name of 'SEASENSE', unit was made in Canada and looked to be of above average quality. The tank measured less than 10 inches high. I think I will add one of these to my 15 as an Aux.

Assuming you have a 15 Sport, the tank of choice is either a Tempo, Moeller or Pate wide/low design, which fit under the driver thwart seat. The proper way to install these
is with the filler cap just behind the seat, so tank does not have to be moved for filling.

They are all 43" wide, 15" wide, and come in heights of 6" (12 gal), 7" (14.5 gal) and 8" (17 gal).
They are available at Bass Pro Outdoor World (Tempo) or Cabela's (Moeller) for about $90 each. Pate Fiberglass Tanks in Miami, are first class, but 3 times as much. All of these were specifically designed for the 13-17' Whaler Sport models. They won't work in the Super Sport models because of the storage unit behind the seat.

Did I hear correctly the Rudy Guilliani just bought a home on the IntraCoastal in Lighthouse Point?

Re Rudy [Guilliani] buying a home in [Lighthouse Point], it turned out to be a pure fabrication by a overeager realtor/spec-home builder. But we would still welcome him I guess.

The clearance available under the thwart seat depends on how it is mounted. The earlier ones are about three inches lower than later models. This can cause confusion when the tanks says "fits Whaler".

Hey Ron, Your lucky day, I was poking around in sailorman's back lot yesterday and saw an original red fiberglass tank from a whaler. I had one like it on my 15' sport it needed fittings but that's easy. Go south to sr 84 in ftlauderdale and head west from us1 and it will be on your left hand side right after the constructon site in case you didn't know where it was.

when you mount the tank make sure you set it back far enough under the rear seat to get your feet compfortly underneath the bench. Mine was too far forward.

I removed the 2 6-gal Tempos from under the rear deck lid of my 87 Super Sport Limited, and replaced it with the 17 gal Tempo mentioned above. It fits perfectly under the seat, with access to the filler cap when the rear deck lid is raised. I believe there is still room back there for the two battery boxes, but I moved them forward underneath the dual consoles to correct the trim a bit. The new fuel tank is great.

I am not sure which model 15 I have, and some homemade changes have been installed. My "85" has a locker behind the rear seat with a hinged top that is original I'm pretty sure. The rear seat has a bare 7" of clearance under it and I don't see a good way to raise it. There is a console for the wheel on the strb side that extends 2/3rds of the width of the beam that is not original from the looks and finish of the mahogany. All other wood is the original bleached Whaler finish.
Even if I were to raise the seat, the locker would prevent the tank from sliding back far enough to give leg room. I don't want to tear everything apart.
So, I guess the best bet will be to go with two or more 6 gallon portables? This will also let me get more weight forward as needed.

Where are you located? I'm in northern California, Sacramento area, and I have 3 6 gallon tempos that I'm no longer using. They're almost certainly not worth the cost of shipping (are they?) but if you're anywhere nearby you could have them for next to nothing.

Ron - it appears you have a Super Sport 15, and this is the one model that won't accomodate the Tempo under seat tank, because of the storage box as you describe.

ditto on that "storage box" larry. Lucky to get a life jacket in that thing. Anyway on my 15 super sport and 15 CC This is what I did: I got a 12gal tempo and put that behind the seat on the port side. On the starboard side(behind the driver for newbies:) I got one of those big heavy duty plastic containers from K-Fart that is a tad bigger than the Tempo. It has a top that kinds locks together when closed. It is not see through and like I said heavy Duty. In here I kept my lifejackets, flares, Fire ext. and spare lines etc. In the bow locker was the anchor and the battery was either under the console or between the rear boxes. It made a clean ship with plenty of gas and storage and pretty equal weight distribution being the 12gal offset my weight etc.

Ron, go to sailorman and look at that tank it was a little different than mine in that it wasn't just a simple rectangular box it had a sloped top. I thought it was for a supersport. I think if you look at the reference section on the 15' there is a pic of super sport with the tank under the seat. I belive it was modified to do so. My 15' had an aftermarket fiberglass console and integrated rear seat. The front seat was a fiberglass box where I stored all my lifejackets. It was really quite nice and if I buy another 15' someday I will build a mahogany box for the front seat and keep the ank under the back seat. Although then I would build a teak planked casting deck over the stern area to then create some more storage similar to that of the ssltd.

Sorry to veer off and daydream with my own repowering task ahead of me it is hard to stay focused at work.

Good Luck and hope to see you out there when I get my new motor on.
