Author Topic:   170 Montauk gas tank options

I recently purchased a 2006 170 Montauk, It came with the twin 6 1/2 gal. gas tanks. I would like to go larger on the tanks. I tried the Moller 26 gal., but it was too close to the rear top opening of the RPS, it also stuck too far out for my liking. I am wondering if anyone has the Moller 20 gal. and how it fits? Thanks Stan

I had replied to you before about this. I used the 20 gallon tank but my 2003 170 Montauk had a large piece of plastic under the cushion on the RPS to which I added a piano hinge so it is now a hatch. This allowed me to push the tank completely under the seat and access the fill cap from under the seat. Also, whoever owned my boat before me, had a 26 gallon Pate tank installed and had drilled a new hole through the floor for the fuel line to relocate it forward so the tank could be pushed all the way under. I'll email you a few pictures.

Stan,
If you want to install a hatch on your RPS see:

Also a search on this site regarding Montauk 170 fuel tank options will keep you busy for a few hours if you haven't yet.

P.S.
Don't be surprised if this thread gets tossed over to the Post Classic section by the site moderator (JimH)

Good luck.

How about a 20 gal tank under the [Reversible Pilot Seat] and installing a round access panel like at the stern of the boat under the seat cushion for fill up?

I installed the 24 gallon Pate tank in my Montauk. I love it.
It's a perfect fit under the pilot seat. Been in my boat for 5 years and no problems at all.

nats,
I would go with the 24 gallon capacity fuel tank solution. With Tempo out of business Moeller is the only game in town as far as plastic fuel tanks being readily available in the market place. I think more people on this site have gone with a 24 gallon solution over the 20. I may be wrong but it seems that way. If it were me, and I was going with a single tank solution, I would go with the maximum capacity I could fit under the RPS since with either a 20 or 24 you're eating up all the space under the RPS. It's not like you're going to have usable extra space for anything other than a fuel tank with the 20 gallon over a 24. People have fit 24's with very practicle fuel cap access. I believe it sticks out far enough aft that an access hatch/portal is not needed. I have seen one install on this site where the fuel cap was put in under the RPS and an access hatch was used to get to it. Plenty of threads and pictures on this site to keep you dreaming about options for quite some time.
