Re: Gas in the bilge
Why can't you use a wire and cut the tank out from the foam using the wire as a saw?

Re: Gas in the bilge
That looks like a real pain in the arse.I hope I don't run into that problem soon.
I did smell gas in the bilge area when I was pumping my primer bulb a million times to get the gas out of my tank a few weeks ago.It took like an hour to get 10 gallons out. I haven't smelled any since,I hope it was a fluke or something. The wire saw trick seems like it should work if you can get to the belly of the tank.

The wire thing sounds good to me also but getting to the belly of the tank has proven difficult. It is not rectangular (see whatknots link to his spec diagram and the shape of the tank) so getting underneath it will be tough with a wire.

Re: Gas in the bilge
After I THOROUGHLY flushed my old tank out with water I cut a couple holes on each side with a hole saw. I then strung a chain through the holes. I placed two 4x4 timbers across the gunnels side by side with a floor jack on top of the timbers. I then shackeled the chains together across the floor jack and popped the tank out by pumping the jack slowly. It's a SNUG fit coming out so take your time so you don't crack your deck like I did.

Gas in the bilge UPDATED
Well, the weather was pretty warm today so I decided to have a crack at the tank again. I got a hand saw and worked around the edges to seperate the foam from the tank as much as I could. Then, I took a 4X4 and layed it across the gunwales and attached a ratchet tie-down to it and the tank. I started ratcheting and after it it tightened up it took a few more clicks and she released. I cranked the tank up quite a ways but the fit is so tight I could not get the tank out. The opening is actually a bit smaller than the tank and it would not come out enough on one end to get it out. I enlisted the help of my neighbor, Carl, and after some deliberation we had another go and actually got to within about an inch of the bottom of the tank. At that point we found the culprit....a while on the stern end in the center about big enough to put my finger in. Carl took my crow bar and pounded it the whole and used a block of wood on the deck for leverage. Then I pounded on the end of the tank with a 3 pound hammer and slowly she came up until we were able to get the end out. After that, of course, it slid right out. Thanks for all the advice, and thanks to Carl for lending a hand. Now, the quest for a new tank begins.
Here come the pictures!!!! Entrance to my V20 cave....  My setup  Here she goes  The culprit  MG]
