I am going to need a new tank for my Formula Jr.
I do not want to take the deck off.

Stupid question here so don't beat me up

Is it a bad idea to secure a tank under the deck on top of the floor?
If you have never seen the space down there on a Jr, there is a ton.

What would be the downsides with one there?

Make the commitment to pop the deck off and do EVERYTHING that
can be done better w/o it.
It's a lot easier than you may first think. You and 3 or 4 friends can lift it off.

If you're going to do a decent resto/reno and you're planning to put in any engine package bigger than what's in it now IMHO you're going to need to pop the deck to reinforce/build-up the hull anyway .

The hull bottom of that thing isn't probably even 1/4'' thick and the stringers might be an inch thick .

Pop that deck ! !

Don't see how you can move the tank up and forward without a significant ride / handling impact. Could be dangerous. Fuel is 6 pounds per gallon. My 22C has a big tank that extends forward (it is the one that once had an outboard), and the handling really improves as the fuel burns off. It's hard to get the bow up on a full tank.

Just my 2 cents. Good luck with the job. I have been postponing the tank upgrade on my 18 for years. Still going at this point.

I agree with George.
I thought it was going to be a daunting task when I had to remove mine, but I was pleasantly surprised at how simple it really was.
I could easily replace the tank in my 22 in a weekend, by myself, using an engine hoist. Deck and hull were only screwed together. (I drilled the screw holes out a bit bigger and through bolted deck/hull together when putting it back on. Mine's an 04. I believe the older boats have some fiberglass "tabs" that will need to be cut). All the wiring and cables stayed with the hull when the deck came off.
I had help removing my deck, but once Lenny set up the lifting support, I found that I was able to put it back on solo.....and could have taken it off solo also.

Do it the right way and remove the deck...period. Any other way its a rig and half assed. When a person who looks at the boat and sees it done that way they will automatically think...Gee I wonder what else is half assed. It will kill the resale as well.

Sorry...you asked. Just not sugar coating it for you.

Pull the deck!

But, you can see from the Wynn Mill plans that a fuel tank can be sort of, through floor mounted. Although in this case it had to be as the boat was wood and had more structure in there.
