I am installing a leaning post in my montauk and would like to put the fuel tank underneath.

I am looking to put in something btwn 19 & 24 gallons and could use some suggestions on the best brands. Even more importantly the dealer about to install my new yamaha 90 said he would have to put an inspection panel in over the tunnel to run the new fuel line. I don't like the idea of cutting any holes in the floor. Has anyone done this?

If your boat is truly a '71, it could not be a Montauk, since they came out in 1974. See the reference section to find out what you have.

But in any case, your Yamaha dealer is probably talking about the hole needed in the floor for the gas line, like the Montauks' have. This is OK to do. You can get the fitting for that from a Whaler Dealer. Your boat was originally designed to have the fuel tanks under the mahogany console, and the gas line goes into the tunnel opening under the console.

Moeller and Tempo both make 26/27 gallon under-seat tanks for the Montauk. You could use one of those. I have heard the Moeller is a better unit, which Cabela's has for $105. For the Tempo, try Bass Pro at $100. Or you could use two Tempo 13's for $40 each, also at Bass Pro. Hose fitting for your engine is extra.

The boat is a `71, but somewhere along the line a fiberglass console was added and pedestal seats were put in ( yep, the wood supports meant nothing to them) so that's the best way to describe it I think.

Let me make sure I understand you. My boat has a hole under the console that my steering, throttle etc. run through. But I want to put the fuel tank under the new seat, not in the console. I would either have to run the fuel line across the floor by my feet and down into where that hole starts or are you saying that I can cut a hole in the deck under the new seat to meet the tunnel and that there is a fitting for this?

Sorry, I can be a little slow sometimes.

All of the Montauks have a "hause pipe" in the floor under the seat for the fuel line from the tanks. See if you can find a Montauk to look at, or maybe someone here can furnish a link to a picture. Get an appropriate Hause pipe fitting, either from a Whaler Dealer (plastic) or from a catalog (SS most likely) then drill the holes, using a hole saw, to fit. I believe the tunnel is formed by an aluminum pipe, so you will have to cut through the aluminum.

Drilling through to the tunnel shouldn't be much of a problem, just make sure that your accurate and seal the edges with epoxy, prior to securing some type of hawsepipe that Larry mentioned.
