I am totally refitting my boat and have been thinking about the fuel tank. I know many of you are using the Tempo plastic tanks. I know some use a stainless or aluminum tank. I have priced a custom aluminum tank to fit under my helm seat and it will be a first class USCG approved job but will cost about $250 for a 24gal tank. Another thing I have to decide upon is the size. Thoughts? Comments? Rex

I am using the Tempo #C2814 28 gallon tank in my Montauk. It fits under the seat perfectly but you do need to slide it aft for filling. It has worked out great.

I have checked those out and the price is $100 less than the aluminum one I am considering so it is certainly attractive. Since I am refitting the boat I believe I will raise the helm seat about 2 or 3 inches. This will help make the tank easier to fill without sliding is back each time. Rex

One of the advantages of getting my boat insurance through Boat/US is getting "Seaworthy", a magizine that examins boating safety based on claims paid by Boat/US and Coast Guard reports.

"Seaworthy" had whole article dedicated to fuel tanks this past summer. while it dealt with enclosed tanks buried in the bilge some where, the information applies to this thread as well.

Based on what I read, I would never use a stainless steel tank. They are the most likely to develope leaks. Many of the claims that Boat? US paid were for fairly young boats.

Aluminum is much better, but why go to the expense of a custom tank when:

Plastic tanks seem to be the best. They leak less, are durable, light, and cheap. Plus static electricity is a far less concern.

Leaks on a Montauk aren't as much of a concern as on an Outrage or Dauntless. The gas fumes won't accumulate so explosions aren't as likely. Catastropic leaks would be plenty obvious, and small leaks should be easy to find.

I would suggest getting one of the Tempo tanks made for a Montauk.

I do have the 28 Gal Tempo and I did raise the seat 2-3 inches so I wouldn't have to slide it to fill it. Hard to say which way I'd go in plastic vs. aluminum if I had to pick again. Whalertim's custom tank sure does look good in aluminum. And $250 seems like a bargain to me. Hard decision. Good luck. I forgot..the mechanical guage on the 28 gal. is so inaccurate that I am constantly looking inside to see what the level really is. Sure would be nice to have a sight tube. Would $250 incluce that?

Yes the aluminum tank includes a gauge. Sounds like y'all really like the Tempo tanks. I think the main reason I don't want one is because of the looks + I dont really know if I need the 28gals. Too bad they dont make a smaller tank which is about 20. I would rather have a nice looking aluminum tank instead of the red one. Decisions, decisions. Rex

My experience with the 6 gallon Tempos in my 13 is that they leak through the "fuel guage" fittings from day one. No amount of sealers, gaskets etc. seems to solve the problem. I think the plastic expands and contracts in the sun too much to ever get a good seal. Has Tempo done anything to improve this situation? I think it would be far better to eliminate the useless guage and just include a translucent site guage in the plastic molding. For now, I am hanging on to the old steel Tempo 12's in my Montauk which do not have this problem. For the record, the mechanical guages on these are remarkably accurate. Does anyone know if you can get a steel fuel tank powder coated (exterior)? I primed and painted the tanks last year, and it is holding up OK, but drips during filling are slowly eroding the paint.

Andy, if you're going to restore that steel fuel tank you need to consider the inside of the tank also. Is it painted inside or is there rust and/or scale? You can get a special paint sold at motorcycle dealerships for this purpose. Don

If you have a really good marine service company / boatbuilder near you, they may have experience spraying Awl-grip. This is a three part epoxy paint that the large yacht and offshore guys use to either re-paint or instead of gelcoat. It is also the paint they use to put color on commercial airlines.

It is nasty stuff to work with, but is virtually indestructible. Unless you have the capabilities and equipment, it is best for a professional. Additionally, US paint makes enough colors that you can probably match the color of your whaler.

andygere posted 01-08-2001 07:06 PM ET (US)     Profile for andygere  Send Email to andygere     
The inside of the steel tanks are not rusty, but also do not appear to be painted. The only rust that can be seen is on the short filler neck, above the level of the fuel. This area could be easily sanded/coated. Is it possible that the inside of the tanks are galvanized? Also, how do you paint the inside of a boat tank (or motorcycle tank for that matter)? Is there specialized equipment or shops that do this work?

Regarding Awl-Grip, is it fuel resistent?

Tempo does also make a 19 gallon tank the part number is F1218. 15"Wx28"Lx12 3/8"H.
There was a problem some time ago with leaking around the gauge on the 6 gallon tanks. Tempo did some redesigning and being a Tempo distributor I haven't seen a problem in several years.

andy, if you're going to paint the outside of the tank go with powder coat; you can't scratch that paint with a key!
To paint the inside of the tank, first get a handfull of nuts & bolts, throw them in the tank with some solvent, cap it and then a-couple-a-times-a-day vigorously shake the tank in all directions. This will remove any scale or rust and roughen up the metal for the paint. I'd do this for about a week. Once you remove all the contents from above, flush the tank out with solvent 'til it's clean, flush again with Prepsol, let dry and then pour in the paint. Turn the tank in all directions until everything's coated and pour out the extra paint. I'll see if I can track down the brand of this inside-the-tank paint. Don

I had two 12 gallon aluminum tanks on my 89 Montauk when I bought it this year in Charleston and they were both leaking and umsightly the only thing OK was the factory rubber floor mounts so I did not want the big BW factory tank or the big Tempo tank. I bought two 12 gallon Tempo tanks but they would not fit under the seat because of the high vent/fuel cap. I replaced with a low profile vented cap from a lawn mower shop and they work fine. I do have to slide them out for fuel. But I like the capablility of removing and being able to physically fuel it up and bring it back to boat if necessary with out putting boat back on trailer. Also I like two tanks as when the first one runs dry you know it is time to come back !

Tempo tells us that the new cap on the BW12 tanks should fit under the Montauk seat. I am going to wait and see. Why they screwed up a perfect tank for a specific application is anyones guess.

lhg posted 01-08-2001 11:24 PM ET (US)     Profile for lhg    
Dick: They did improve the new "Ultra PBW12" tank with better fittings, and a larger capacity to 13 gallons. In some repects, this makes sense for pre-mixers, since at 50 to 1, 12 1/2 gallons of gas takes a qt of oil, for a total of 12 3/4 gallons. The problem is they had to make the tank higher to get the extra capacity, plus they added the high profile top. I agree, doesn't make sense. Maybe they felt this is a decreasing market as the boats get older. Bass Pro sells this tank, incidentally, for $39.95., a good price.

I agree the extra capacity was a + but it made the tank to tall. As a Tempo distributor and a Montauk owner I have talked to them about this problem and they have said thet they are reducing the heighth of the tank so it will again fit.

I represent Mirax, a fuel tank manufacturer who probably made a number of the original tanks out there.

The most common was a 12-gallon tank with mechanical gauge with rough dimensions of 12 x 14 x 18.5

The fittings were located in three different locations depending on which model boat. I am trying to put a production run together, so if anybody has interest, please let me know.

We can make virtually any size fuel tank from aluminum, any configuration. ALso, the aluminized steel line is being improved by adding a plastic (poly) coat rather than paint. The poly coat is the same sprayed on plastic used for sprayed truck bed liners.

Feel free to email me about the 12-gallon tank if you are looking for one, or any other tank you may be looking for. 12-gallon aluminum tanks are in the $195 range and aluminized steel tanks run about $20 to $30 less expensive (with the poly coat).

All tanks include gauge, withdrawal, and cap (if required).

Feel free to email me at ollie@mirax.com or fax me at 314-752-5500.

I would also like to address some of the misconceptions of metal and plastic fuel tanks.

Plastic fuel tanks are not safe. The risk of static electricity explosion is GREATER in plastic tanks as they are not easily grounded and rarely grounded properly. One example is plastic jugs in truck beds - very dangerous. Either use a metal container or make sure the jugs are secured, preferably with a cloth buffer between the jug and the truck bed (whether it's plastic or metal bed).

Safety: Plastic tanks pass the fire test on a MINIMUM side of the requirement. Watching this test will make you NEVER buy a car or boat with a plastic tank in it. The plastic eventually melts, releasing fuel and causing an explosion. Metal tanks, however, force the fuel through the vent at a consistent rate as the tank does not change shape as the plastic tanks distort. Therefore, on a metal tank, the fuel burns at a consistant rate where it is vented, but the explosion typical of plastic tanks does not occur. The tank is simply pressurized and the fuel slowly forced out.

Another falsehood is plastic is less expensive than metal. Many times metal tanks are LESS expensive than plastic. Plastic MUST be run in quanity to produce a product at a reasonable dollar figure. It also costs hundreds of thousands of dollars for all the equipment to mold plastic tanks.

Metal prices (treated steel and aluminum) are way way way down, and plastic keeps going up. Also, metal tanks are much more readily recycled. Plastic tanks are NOT environmentally friendly. Another point,

Sorry, I'll continue later, urgent matters here. Email me for more info or I'll try to post later.

Until recently BW has always exclusively used aluminium for built-in tanks, but recently I have noticed the Dauntless series is now using plastic built-ins. Would this be a safety concern? At least internal corrosion from condensation should not be a problem.

Regarding the plastic above deck Tempo tanks, I have found that as long as I leave the cap vent open, avoiding pressure build-up, and use teflon tape on ALL fitting threads, leakage is not a problem.

Larry, I run 2 6gal. Tempo tanks in my `16 Currituck, and you`re right, I just back off on the vent screw ever so slightly and I have no problems with bloat or leaks. One time I forgot on one of them for a week and that sucker blew up to as hard as a rock, but never blew the seems, that is a testement to the quality I would think. Regards-Jack Graner.

Does anyone know if Pate Plastics is still in business. I bought a 12 gal. fiberglass tank from them back in 1990. Great tank, desert tan gelcoat, no fuel gauge, but with a clear site window running from top to bottom. At that time they probably made a couple dozen different sized fiberglass gas tanks. I believe they were located in the Miami area.

I called Pate Plastics (actually a fiberglass tank) last week and they sent me a fax with sizes/prices. They make 2 tanks they suggest for a Montauk a 24gal and a 27gal. My cost was about $260 for the 24 and $275 for the 27. The literature says they will paint the tank desert tan but doesn't mention an additional cost. Looks like nice stuff but mucho $$. Rex

I believe Pate's price includes the color of your choice. The tank I ordered back in 1990 from them matched my 15 SS perfectly. The tank looked like the factory installed it.

The threaded fittings on the Tempos are not the major problem for leaks. The (useless) plastic fuel guages are held to the tank with self-tapping screws, and seal with a gasket. It is at this joint that is impossible to get a good seal. Even with the vent open, if the tank is full or nearly so, it will eventually weep at this joint. Partially filling the tanks is not a good solution either, because when accelerating from rest or in heavy seas, the sloshing is enough to move fuel to the top of the tank. If Tempo got rid of the silly guage and went to a site guage they may be OK. Because the steel tanks are dimensionally stable at the typical range of temperatures encountered, the guages on my 21 year old steelies don't leak, vent open or not (By the way, the old mechanical guages in my steel tanks are surprisingly accurate). I would expect fiberglass to be OK in this regard. How are the fuel line fittings attached to the Pate tanks? Does Pate have a website? My feeling is that the only advantage of plastic tanks is low initial cost. I would like to see an alternative that is more reasonably priced. $400 for a pair of new steel 12's is pretty steep.

The fuel line fittings on my Pate appear to
be an pipe thread hole tapped into a flat piece
of metal which is bonded to the tank. There
are two such fittings, one at each top rear
corner of the tank. The filler is a similar
piece bonded into the middle of the top rear
of the tank.

One of the fuel line fittings is plugged, the
other has the pickup.

I did have the pickup tube come unsoldered
from the fitting when about 10 miles from
the dock. We removed the rubber hose from
the pickup and shoved it in the filler, and
taped the bulb to the filler and got home
no sweat. Even stopped to do another dive.
The original solder job was really ugly.
It took me about five minutes at home to
resolder it (after a thorough air out of
the line and fitting).

I called Pate this morning and unfortunately, they do not have 12 / 13 gallon tanks that will fit under the Nauset and Sakonet consoles. The minimum width of their tanks are 15.25"

Forget the aluminum tanks. According to the Coast Guard "almost every aluminum tank examined had some form of corrosion." Boating Magazine, Feb. 2001 issue. The article said you should never buy an aluminum tank made from 0.090" or thinner aluminum sheets. Case closed.

I got this directly from Chevron's website:



"Filling a Container


There have been several fires at service stations when customers placed metal containers on plastic bed liners in pickup trucks while filling the containers with gasoline. Filling a container is a special situation that requires extra precautions:

Use only an UL-approved plastic or metal container.

Shut off the vehicle's engine.

Place the container on the ground a safe distance from the vehicle, other customers,
and traffic. Don't fill a container in or on a car or truck.

Keep the nozzle in contact with the container during filling.

Control the nozzle valve manually; do not latch it open. If the nozzle is fitted with a
fume-recycling device, the filler-spout seal must be compressed to activate the dispenser.

Do not smoke.

Avoid breathing gasoline fumes. Flowing gasoline generates a static electric charge that builds up on the gasoline in the receiving container. If the charge isn't given an opportunity to dissipate, it could jump from the container to the metal spout of the dispenser nozzle as a static spark. If a spark occurs near the open mouth of the container where the concentration of gasoline vapor and air is in the flammable range, it could ignite the gasoline. Putting the container on the ground and keeping the nozzle in contact with the container help dissipate the static charge. The charge will dissipate more slowly from a container being filled on an insulating
surface carpet in the trunk of a car and on the bed of a utility vehicle or the plastic bed liner of a pickup truck. Placing the container on the ground has the secondary benefit that an accidental spill won't contaminate the vehicle. Fill the container only about 95% full. This leaves room for gasoline to expand if it warms up in storage. Without an air space, expansion will force liquid gasoline out of the container or distort the container."

Notice that in the first paragraph that the problem is due to filling metal tanks in pickup with palstic bedliners. Not plastic tanks!!!

Notice that the last paragraph suggests not completely filling your tank. This will help prevent spills which are enviromentally unwise and like it or not could result in a big fine. The EPA and the Coast Guard can both nail you with large fines for fuel spills, regardless if the spill is due to defective tank design or not.

I have the two Mirax fuel tank setup on our 1984 Montauk. Both tanks have a fuel line clamped on the tank end, routed through the tunnel with the primer bulbs and quick connectors on the aft end. One of the quick connector on the aft end of the fuel line broke today on the way to the bay. The lines are 1/4" and the replacement yahama connectors are 3/8". New project, replace the fuel lines. Question. Should I install male quick connectors to my tanks so that there is only one fuel line to the stern, and the tanks can be removed? What are the experences with dual tank fuel lines?

I just received a 27 gallon Pate Tank for my Montauk.
I looked inside tonight and noticed the end of the pickup tube appears to be mostly clogged (looks like solder).
This doesn't look like a screen for keeping junk out of my fuel line.
I am going to call Pate in the morning and see if they can recommend some way to clear the pickup without having to send it back to Miami.
On the odd chance that anyone else had this problem, any recommendations....?

My Pate has pickup tube that goes down, and
bends parallel to the bottom of the tank.
The bottom of the tube has a slot with a
screen soldered on it. You can't really see
the screen. I suspect you are seeing the
solder that holds the screen on.

You can pull the tube out just by unscrewing
the fitting where it comes out. If you do
that, be sure to inspect the solder joint
where the tube attaches to the top fitting.
Mine had a cold solder joint there and the
tube fell into the tank after a while.
We got the boat home by removing the hose
from the QD and shoving it in the tank filler
tube. It took about 10 minutes to resolder
at home.

My read of the CG regulations are that "portable" fuel tanks must be less than 7 gallons capacity. Any fuel tank over 7 gallons is not a coonsiderd a "portable" tank and must have a vent which is plumbed overboard. In theory, any tank larger than 7 gallons on board your boat without an overboard vent would fail a courtesy safety inspection done by the coast guard auxiliary, assuming the inspector knew the regulations. The reason the industry gets away with this is because the boat/engine manufacturers don't sell the larger "portable" tanks, and the tank manufacturers (tempo/moeller, etc.), are selling a tank only, and are not responsible for how you use it. This is a gray area in the safety regs which has always bothered me, possibly leaving the boat owner on the hook if something goes wrong. I don't know how an insurance company would respond to a claim under these circumstances. This issue is particularly important to small Whaler owners since there appears to be a whole series of oversized "portable" tanks developed just for them. Any comments?

I removed and inspected the pickup tube in my Pate tank.
It turns out the screens are on the bottom side of the tube and I was looking at the solder on the end.
It looks good.
I did put some teflon tape on the threads on both the pickup tube and the cap on the other tap in the tank. I don't know why the threads weren't already taped. Maybe its unnecessary.

Does anyone know if Tempo has redesigned the 12 gallon tank with a lower cap so it fits under the Montauk seat?
lhg posted 04-16-2001 06:46 PM ET (US)     Profile for lhg    
Tempo shows the height of this new tank (ULTRA PBW12) as 14". Cap height is extra, but I think you can saw off the "ears" to reduce the height, or maybe buy one of their lower profile tops, assuming threads are the same. Incidentally, it's now a 13 gallon tank, to enhance pre-mixing (1 qt oil and 12 1/2 gallons for 50 to 1). Bass Pro sells them for $39.95. These have to pulled out to be filled, and gas line switched between tanks.

But unless you need portability for filling, I'd get the 28 gallon tank, and teak block hold-down kit instead. Tank is $105 bought right. Hold down kit is about $15. Install the tank back far enough to leave "heel" space when driving, and so the tank cap is behind the seat for filling without moving it. Instead of the twin Whaler gas tank mats, I'd put some "dry-dek", cut to fit, under the tank. Washdown water can then run under it.

If you must have the new 13 gallon tanks, and still can't get them to fit, consider raising the Montauk seat on some 3/4" or 1 1/2"black starboard blocks. You'll like the extra height.

I am a wholesale distributor and Tempo is one of my lines.

The PBW12 will not fit under a Montauk seat. I tried one from the last batch we got in just to check if they had lowered the profile.

I run the Tempo 28 gal in my Montauk and it fits great.

I'm curious because I'm thinking of redoing the installation of the Tempo 28 on my Montauk. The tank is currently chocked so that the fill hole is accessable without moving the tank. That means that the tank isn't completely under the seat. There is probably 4" of the tank that sticks out toward the back of the boat. It would be more comfortable for passengers sitting in the RPS when facing backward if the tank was flush.

What about using a pair of transom tie-down straps to secure the tank? A 1 or 2" wide by 4' strap connected from one leg of the RPS to the other, one in front and one in back, I think would do the job. That would mean I wouldn't have to drill more holes in the deck for the teak chocks. To fill the tank I would just loosen the rear strap and slide the tank back.

Any thoughts?

Thanks,
Barry

RWM. There is a lot of good info on this thread. I do have it. See my post above. I really like it. Really. Would do it again in a heartbeat no question. I used blocks made of teak to raise the seat height to get to the filler cap without sliding in and out although that wouldn't be much of a problem anyway. Just my way of doing it. Next time I have to refinish the teak I'll just make new ones out of starboard though. Less maintenance. As a matter of fact when the seat material gives out (soon) I'll simply have a little half/circle cut in the middle back of the seat cushion just above the filler cap (and wood backing, of course) just to make it just a little easier to access. I have pics if you want me to email it to you.

I looked at my tank yesterday and have this to post.
27 gal pate that is on the factory whaler pads that have been notched out on the insides to fit the tank. It fits perfectly in the pads and has NO tiedown or blocks. The mats are screwed to the deck and the tank fits inside the mats. In the last 2 months, the only time it has moved was when we had 6 inches of rain overnight and I left the plug in and it floated.
I bailed the boat and then slid it back into place again.

I installed the tempo but I did like the old pate better. I cut the centerline edges on the pads bigshot talked about and just put the tank on these pads no straps. I figured the old one didn't have a strap, so why not? I also cut the tabs off the new gas cap so I could get it off without moving the tank or the seat. I thought I read somewhere here that someone got a new cap from a lawnmower deal that fit.

The original whaler pads are long gone. I think for the short term I will put the Tempo on a thin rubber mat (to reduce sliding) and wrap a hold down strap around the seat to keep it more or less in place. Maybe for next year I will raise the seat and use chocks and straps...Bob M.

Just for everyone's consideration, any fuel tank of this size is considered to be a permanent fuel tank by the USGS, even if it is a portable.

To conform to the regulations, it must be properly strapped down. I used nylon strapping, strap connectors and ss loops for the deck for my Tempo 28 in my Montauk. Works fairly well, as it never moves, just set on top of the Whaler fuel pads. Only thing is I have to slide it out to fill it up.

An update on my fuel tank. I switched from a 19gal. Tempo to a 28 gal.( C2814) Total nightmare. Immediate engine problems....(read my past posts ). Finally, the tank split while sitting in the driveway. Apparently, the venting device was faulty. I am glad to be rid of it, and will not be replacing it. I'll stick with the old tank and check out a Pate; perhaps I'll just get an extra 6.5 gallon tank for longer trips.
That tank was nothing but trouble!
While it was installed, I had a thick strap on the front side, ( horizontally) and two bungees from the side of the RPS to the rear of the tank, anchored to the deck. It worked just fine. Too bad the tank did not.

I have the Tempo 28 in my 99 Montauk and is works out well. I removed the tank pads and installed two for and aft cleats that fit the grooves in the tank. The tank is secured by a nylon strap all the way around it and the seat bases. Pop the quick release on the strap and slide the tank aft to fill.
I will senp you a pic.

Tightpenny - If what you say is true, about the tank having to be straped down, how does BW get away without strapping them down when they come out of the dealer? I'm 95% sure my old pate never, ever, had a strap around it. There are no old screw holes in the deck where a strap could have been attached and no markings on the tank where straps might have been.

Mine is factory with no strap and I do NOT have to move it to fill. It never moves and I have been VERY airborne in that thing.

When I test drove and took home my 2001 Montauk there were no straps on the two plastic six gallon tanks. They slid all over the place. I took her back to the dealer and they installed two black nylon straps.

I just installed my new 28 gallon Tempo and am okay happy with the installation. The teak mounting blocks are on back order at West Marine (F.Y.I.).

I didn't like the idea of having to move my tank aft for filling so I installed it four inches aft. I removed the two gray rubber mats. I was able to use the two outboard eyelets and connect both black nylon straps together to go around the tank.

I bent up three aluminum angles at work (acid etched and alodined them). Then using existings holes in the boat I put one on each side and one aft. The holes from the rubber mats were not square so I had to mount the angles in two diferent directions on the sides.

I had to bring the fuel line above the deck so it would not get pinched.

To avoid the hassles associated with limited access to the gas fill on the stock tank on my '86 Montauk I hinged the seat.

Unbolted the seat for the right and left support. Bolted a quality stainless hinge on the front on each support and bolted the seat back down to the hinge.

It's unnoticable, allows me to prop the seat up for refueling with a soda can, small piece of wood, etc.. Can also tilt the seat more for instant and easy access to the entire top of the tank...

good luck...

Since I have been unable to find a replacement, does anyone have any suggestions or examples of what they have used?

Thanks

I haven't really read every word of this post, so someone may have mentioned this:

I opted for two 13-gal Tempos instead of one 19-gal, or one 28-gal tank in my Montauk. The reason is that as long as you don't cruise in a straight line with the weather at your back, you'll always be able to make it back home when the 1st tank runs out. In this way, I don't have to keep a constant eye on the fuel level. Also, ever try to lift a full 28-gal tank. It's over 200 lbs. Tanks this large eliminate the option of driving it to the station (usually cheaper) in the back of your pick-up.

The tank mats are available from any Boston Whaler dealer. They are spendy and I believe the only color available is grey.

Hey everybody-
I was at a local marina the other day, and they guy had a bunch of new Tempo tanks on display. One thing I noticed was that half of them had a redesigned lower profile gas cap. He wouldn't sell me the caps off of the new tanks, but directed me to an OMC cap P/N 0502936. They are about 3/4" lower than the stock Tempo caps, and are vented as well.
I bought two of them for about $7. each, and they fit perfectly! No need to shave off the ears on the Tempo caps.

There's a photo of the two caps side by side in the photo section of my new site. It's in the album titled "Paul's '79 Montauk"

Just thought I'd pass it along.

Anyways, here's another fuel cap replacement for the Tempo: Quicksilver P/N 36-816976Q 1. One and a half inches high vs. 58" (I'm pretty sure) for the Tempo. Just bought a pair for $13 and change, tax included.

I installed twin 7.5 gal Tempo plastic tanks under my mahogany console (should work fine under the seat as well. I carry an additionl pair of 6.5's under my forward seat for spares. 7.5 is considered the largest portable tank approved for vessel safety checks by the USCG Auxiliary. Anything over 7.5 is too heavy to lift in or out of the boat when full. Filling a tank in a Whaler is not considered fool proof as a spill inside the hull puts the gas/fumes down in the tunnel inside the hull. As most wiring runs thru this tunnel, any short can make for a very bad day. Considering the range I get with my 50 HP 2 stroke (in excess of 100 NM) I can't see the value of going with a single BIG tank. My 7.5's cost less than $40 each and the 6.5's were about $25 or so.

I have a 27 gallon Pate in my Montauk and it works great. It is the original tank and shows no weak areas. As far as capacity, it depends on what you use it for. With a midrange outbourd like a Montauk would carry, I can't imagine getting less than 18 gallon capacity. More than once on a day of fishing I have run out over20 gallons. This is going a couple miles out and trolling for Kings or Spanish. I understand not everybody may take their Montauk offshore but I have also easily run 14-15 gallons running the river and pulling skiers, etc. Besides, I would rather have a few gallons to spare if the weather starts to turn and you need to high tail it home.

One thing that hasn't apparently been mentioned is the difficulty in adding gas to smaller tanks and getting the oil gas mixture on the money. With the larger tanks (greater than 6 gallons) adding an additional 6, 12 or even 18 and getting the mixture in the tank correct is a snap. When I was runnig two 6 gallon tanks pouring one to the other and filling a six gallon and topping of the other was always a mixture pain at the gas station. Yeah I could use the graduated cylinder that is sold at West Marine, but I would still end up with a open partially used oil bottle. Now with the Pate 27 it is no longer a problem, and I don't worry about having the gas to get back to the dock.

I have a Tempo 28 in my Montauk that was there when I bought the boat. It was mounted so that it protruded 6 or 8 inches out the back of the RPS. The cap was too tall to fit it under the RPS.

After much experimentation and buying half a dozen or so low profile caps that didn't fit I found one at the local Wal-Mart, Yard & Garden department, that fits like it was made for it: $3.97. It is labeled for a variety of yard tractors.

The big tank now nestles under the seat just fine. The trade off, of course, is that I have to loosen the straps and slide it out to fill it or to look at the very unreliable guage. With Suzi DF70 on board I don't need to do that very often.

He has 20+ years there and has replaced more s/s tanks then all the other ones combined. I just read not to long ago how plastic tanks were dangerous, so now I'm really confused.

I have an aluminum tank that is built in under the RPS of my Montauk. The tank extends about 5 inches aft of the aft end of the RPS to allow for room for the refilling spout and cap. \

The tank has large capacity which is great for me as I have no nearby marine fueling.

The system seems to work great and would recommend it.

My 22 gal Pate "Glasstank was installed 23 years ago. I am on my 3rd engine (many many hours of use in South Louisiana.) The 22 gal was what available in those days. I have never had a seconds trouble save having to replace the gas cap about 10 yrs ago. It fits perfectly under my RPS. It fits in mats and doesnt need to be moved for filling. I have yet to run out of fuel. When on long 150 mile+ trips I have carried xtra portable tanks.
This product is undoubtly one of the best investments (along with the Montauk) that I have ever made. My son, who grew up in the old Montauk, just bought a new design 170 Montauk. We are going to install his new Pate 27 gal in his boat this weekend.
We wouldn't have any other tank.

I have the Tempo 14 gallon tank on my Montauk. It has only one "depressed" area for a hold down strap. This didn't seem to be enough so I installed a set of Igloo Cooler hold down corners. The ones the coolers set down into. Works like a champ. I don't use the straps just the corners. I am going to the 19 gallon tank. It is the same length x width but the height with cap is too tall with out sliding the tank out as was mentioned earlier in this post. I fabricated two brackets out of stainless that will raise my seat. I can then get the cap off and have room to fuel.

I recently bought a 1971 16'7 model Whaler with a center consule and a 1986 75hp Evinrude. The motor was shot and I had new pistons, seals and head installed, along with a used set of carbs. The mechanic that did the work partially blamed the blown #3 piston on the previous owners use of 6 gallon Tempo tanks. These are the tanks with the fuel line molded into the tank shape. He says that this model tank does not supply the engine with enough gas at acceleration which leads to engine damage due to lack of lubrication. I was wondering if anyone else has had similar problems with these tanks? I have asked around to all the local marine shops and they have never heard of this problem. Any help would be appreciated.

I've got an 83 Montauk with a 24 gallon red fiberglass tank. Concerned that within the next year, that gas on my lake will be an Ethanol mix and have read recently that older fiberglass tanks used resins that degrade when exposed to ethanol, resulting in damage to tank and engine. Anyone know whether the new [fiberglass] tanks use resins/polymers immune to the ethanol problem?

I would be very careful with [fiberglass] tanks with the new [fuels containing a blend of gasoline and ethanol]. I talked to [someone] at [a fiberglass fuel tank manufacturer] and they said they have not had any problems yet, but I'm not sure if there has been enough time to tell if the [fuels containing a blend of gasoline and ethanol] will attack their tanks.

I replaced a failed Tempo 28 gallon tank (the one made for the Montauk) with a model C27 Pate last year.

The Tempo after five years was deforming with the middle bulging out, and the top bending in. The seal around the fuel pickup began leaking like the Titanic after the iceberg. No more flexible tanks for my 2000 Montauk.

The C27 fits under the seat but in order to use the fuel line opening in the deck,and the stock fuel tank pads, the pads had to be moved forward a bit, and cut to allow the Pate to sit level.

Filling the C27 requires that the tank be moved toward the stern in order to place the gas nozzle into the tank. This is much easier to do with only 4 or 5 gallons in the tank than would be half full or higher. There is no easy way to grab the tank to lift it above the tank pads. I am thinking of using an additional nylon strap to lift the tank over the stern edge of the tank pads, which should allow me something to grab onto.

There have been many anecdotal reports and citations of information regarding fiberglass fuel tanks which have been attributed to all sorts of unidentified people and provided with little authentication. I do not consider any of these to be authoritative. If you are interested in accurate information with proper references about fiberglass fuel tanks and newer blends of gasoline and ethanol, you should read this article:

http://continuouswave.com/ubb/Forum1/HTML/012667.html

In my opinion, that article contains authoritative information and you can make a decision based on it.
