Yeah, if it would fit. It looks like about 40 - 45 gal is the best I am going to find without going custom. But temporarily I will just carry a 6.5 portable with me on long trips.
 
Thanks to everyone . Fishing in a tournamnet this weekend and will probably install the new tank Monday morning.Thanks to all who chimed in.Im gonna foam it in for sure. I like the idea of the mat from Home Cheapo.Thanks again. Will post pictures while i do it.

24" W x 60" L x 10" Deep...will she go ??? ...go back to 1st page and find his link to that tank... :D ...
 
One item to note about that tank: I had to move a frame forward a bit for the tank to fit. I accepted that because from what I could see of the frame, it was in poor shape. What I found out, was the only function it performed was holding the foam in place. It was not structurally attached to the boat. There was a 1x1 piece of wood in the corners with two screws goin to the frame and 2 screws going the side of the hull. I took that out, cut a new frame and glassed it in a little further forward than it was so the tank could fit. You can see the new frame in the pictures. Just keep that in mind. I was going to make that tank fit anyway, because I bought it from a guy at work for about half price.

Umm, I'd be curious as to who said those bulkheads, or wood frame between the stringer provided no structural support. ??? I could be windtalk'n here but I think they are suppose to help minimize flex as well as adding support to the stringers. Of course, I'm no engineer and I haven't stayed at a holiday inn express lately, so I could just be talk'n out my whazoo ::)
 
Jeff,

I agree with you that the frames are supposed to be structural members of the boat. However, once I removed all the foam, I found out that the frame just forward of the fuel tank was not serving a structural purpose. I only held the foam in place because after I removed two screws from each side the frame fell out. That is why I cut new wood and fiberglassed in a new frame as an intergral structural member of the boat.

Did any of you guys have to cut your deck to get your old tank out ?? About 3/4 of my tank was below the deck and had to be cut. Just curious.

I used an anti fatigue mat that I bought at Home cheapo.  The mat is what they use in restaurant kitchens.  It was around $20.  It's a little less than 1" thick.  I cut it into 3 long strips and put my tank on that.  I used some wood on top to hold it in place and used a small amount of foam only in each corner.  It is a plastic 52 gallon tank. http://www.overtons.com/modperl/product/details.cgi?r=view&i=30458
I'll post some pictures soon - hopefully tonight

I thought the plastic tanks had problems with the new ethanol gas.

I hope I don't bring you bad news but if that frame was only in there to hold the foam and now you glassed it in to help provide structural support you may have put the hull in a rigid bind (not let the hull flex) which may cause stress cracks. I've never done the numbers on my V-20 (i/o) but I know if you move or make a new gas tank up fwd it adds additional weight to that area fo the bow and may not let the bow relax after take off and cause a binding area with the new gas tank and additional port to stbd framing. If you just galssed it in and didn't fully secure it prior to glassing then just glasssing it won't cause a 100% rigid member.
 
I think if the Poly tanks want CG approval they have to be baffled... But I could just be baffled myself ::)
 
The 52 gal I have I don't believe has baffles in it. I don't believe the 40 gal I took out had baffles either.

garagenc,
the frame I added is has a couple of screws to the stringer then glassed in. The frame that came out looked like someone messed around with it prior to me taking it out. It had some fiberglass on the lower half, but nothing on the upper half, which eventually made the whole thing mush.
