Has anyone tried to switch their fuel tank and the ice chest on a montauk? I have a Pate 24 gallon tank that weighs 150# when full. Seems to make sense to move that wieght forward to better distribute weight. Already have moved my 2 batteries to console. Also seems to make sense to have the ice chest in rear under seat where fish are brought into the boat. 2" spacers have already raised my pilot seat. Just a thought. Like feedback pro and con. How would you secure the tank? Etc.

One possible con is regulations. I may be speaking out of school here, but I seem to remember a regulation (when researching another fuel tank question from this forum) that had to do with the differences in how "tough" tanks must be built if they are going to be used in the forward half of the boat.

Other than that, and if you can figure out if your current tank meets these requirements, it should result in a smoother ride with the weight forward. - I would be interested to see how much fuel slops up through the ventcap in a chop though.

I like your idea. I'm thinking of doing the exact same thing after I get a season under my belt on the new boat. I would like to fabricate a seat to go over a tank mounted in front of the console. This would also give me an area to mount a number of rod holders.

Let me know if you do it and how the boat rides in waves.

I think it might be a mistake.

A) you can't sit on the Pate.

B) Montauk's ride smoother with weight in the aft. My boat rides like a Caddy with the heavier 4 stroke then it did with the 90 Yamaha.

C) You NEED to run the fuel line under the deck....possible being tunnel is under console but so are batteries. i don't want spark and gas anywhere near each other.

D) If it catches fire do you want to burn your face or your ass? Joke

E) Might not fit being the way the bow is uneven. You want a solid support under it so she won't crack. Weighing about 200lbs full is a lot of stress on the thin glass on bottom.

Bigshot, I do not have real-life expererience with the 170 yet but will after this year.

A) You can fabricate a frame around the tank and put a nice comfortable seat on top of the tank (or swivel fighting seat for those people going for bigger game - tuna, shark, etc.)

B) I'll find out about afer a year. You may be right. I'll have to see how the 2 passengers at 400+ lbs ride back there with a 4S on the back.

C) this is really not an issue. Gas lines do no typically leak gas except at the fittings on a poorly maintained boat. What's the real likely hood of you not smelling the gas fumes and having loose fitting terminals at the battery to cause a spark.

E) If I had a cooler in front of the console I would have a 200+lb person on top of it when going thru some nasty cuts and especially going over wakes.

Don't forget the 200+ lbs of beer in the cooler...

Seriously, I think it might not fit. The base of that tank is 19"w x 30 1/4"L. No need to add to the additional 1.5" for the mounting blocks, because your space problem is going to be at the front (bow) corners of the tank where they meet the hull's bow rise. I have a 72 quart Igloo that measures 16 1/8"W x 29 7/16"L, and it is a comfortable fit, but it is elevated by the cooler cleats. I'm betting the tank doesn't fit. I'll be down at the boat in the morning, and measure that space if I can remember to do it.

Anyway, just to be a pain, I'm going to throw out the suggestion that mounting your batteries in the console can be problematic. I recently discussed this project with a marine mechanic who insisted that the additional pounding the battery would endure in the center of a Montauk was bad for the battery and might lead to leakage and/or premature failure. He recommended this project be done with "gel" based batteries, if at all.

Truth be told, I'm not moving my battery because of the big, bald spots on the nonskid where it has been strapped to the stern for the last 17 years. (Rubber pad your stern mounted battery boxes now, guys, you may thank yourself later!) I plan on hiding it with a stern seat.

I would not do it! Bigshot makes some good points and placing a fuel tank that far forward will put lots of stress on the tank if you are ever in some really rough water. A friend of mine, Morgan Gilreath of DeLand, Fla had a custom aluminum fuel tank made to fit forward of his Montauk's console and on trip to Bahamas the tank ruptured and 30 or so gallons of fuel washed accross the deck and out the drain. No fire or explosion but not enough fuel remaining to finish trip (had to lend him my spare 6 gal tank as did others). This fuel tank thing is serious business so my advice is to do the safest thing and leave tank under the helm seat! Happy Whalin'... Clark... Spruce Creek Navy/GLN

How (or why) did the tank rupture? Do you have any pictures of Morgan's setup?

I wouldn't do it personally, but there is/was a seat option that goes in front of the console on the Montauk which was made to store a porta-potty under, the frame mounts to the console and deck.... you could probably put a gas tank under it, but not a 27 gallon. Mine came with the option from the factory. I changed it....I took the seat off, measured the teak chocks on a Montauk at the boat show, bought the teak and built my own chocks and put in a 94 quart cooler seat front of my console. I have the bench seat in the rafters of my garage......It's the only one I've seen in person.

That seat was kinda popular but more so on Outrages. Cheaper to put a cooler seat in a montauk.

To some that already have your mind made up, do the conversion. After owning many whalers and how they handle, I would not. Just my $.02

Cape, don't know if it split at a weld or what since tank had a platform built over it and no pics, it was back in 1996 I believe. The failure was most likely caused by the pounding we took going into a 15 mph headwind. I had a 27 gal Pate tank under pilot seat on my 17 Whaler Newport and a six gal portable tank as far back in stern as possible and I had no problem... also twin batts in stern.. Clark... SCN

I appreciate all the posts. My tank is the Pate 24 gallon. I enjoy a challenge and believe that even a classic can be improved. If it can be done effectively, some people on this forum will "make a way." Looking forward to uncovering her tomorrow and begin the process. Someone has already emailed me the dimensions of the tank. Thanks again.

Just an observation here but if it made sense from a safety and performance perspective to put the fuel tank forward of the console, wouldn't Whaler have done that?

The Whaler Owner's Manual for 9 to 17 foot models generally advises that "[m]ost 9-17' models ride best with weight positioned from mid-ship aft." It specifically advises "[a]ll Whaler 17 foot models should be run with the bow light and high for a comfortable ride. This trim will produce faster and more efficient engine speeds." A fuel tank in front of the console would seem to run contrary to this advice.

Some tanks have no baffles (internal dividers to pervent sloshing of fuel) and would not be suitable for fwd locations.

Trailer tongue weight will increase also.
