What type of fuel tank works well with the 17 to increase capacity?

Last week I installed a Pate C27 in my 2004 170. It fits great under the RPS. I used 4 white Starboard blocks with stainless eye straps mounted on them to prevent the tank from moving fore and aft. These eye straps are the ones used for the straps on Bimini tops. I used white stretch cords with stainless hooks to secure the tank to the deck. I also put a Gortex gasket material under the tank to protect the non-skid floor and to provide a cushioned surface under it. If I remember right the C27 shipped to my house was around 405.00. If you are not a dealer, Pate requires you to send a check to them in FL.

Regarding the quick fix using the two 13 gallon tempo tanks, does the install require any drilling or does it use the existing eye straps? Looks as though it will slot right in. Just checking.

Jonathan, You do have to drill new holes for the straps. I think I used the same hardware but different longer straps. The clearance is very tight at each tank cap and hose connection, even with low profile caps. They will come in contact with the RPS when sliding the tanks out. JimB

The 24 gallon tank fits nicely under the rps on the 170. You must seal up the original hold downs from the two 6 gallon tanks. Then drill new holes for the pate tank (either the 24 or 27 gallon tank).

The 24 has more room. So its a bit easier to remove the gas cap.

Putting a rubber sheet below the tank is a good idea so it won't slide and also will protect the deck.

Various people use poly cords (24" length) and some people don't use them.

Here is a well illustrated review/installation of a Pate C24 Fuel Tank.

I find no negative to having the two 13 gallon tanks. I almost prefer having two isolated fuel supplies. It is an excellent way to go for 2 x $40 (tanks) + straps + fittings + caps = $150.

BTW, they really only hold 12 gallons.

Off topic, gas is $2.49/gallon for 89 octane on Cape Cod.

I just ordered two Tempo 13 gal. tanks from Bass Pro Shops but could not find the low profile caps that others have been referring to. The Tempo site only lists one cap for the 13 gallon tanks. Can anybody give me a part number and/or supplier for these? Will the tanks still fit under the 170 Montauk RPS the with the stock caps?


Maximus posted 06-01-2004 06:55 PM ET (US)     Profile for Maximus  Send Email to Maximus     
Low profile, vented gas caps are available at HomeDepot for about $3/each. They are in the lawn mower maintenance section. I think the 2 1/8 cap size is an industry standard.

The second part of your question:

The 13 gallon Tempo tanks will not fit with the stock caps. The stock caps are about 3 inches tall. With the low profile caps and the Mercury fuel connectors, the tanks will fit under the RPS. There is a small amount of interference with the plastic trim piece. You will also notice a difference with the tanks full vs. empty. The full tanks fit great, while the empty tanks stand taller.

My setup is identical to Barney's.

Thanks for the reply. I will head to The Home Depot tonight to buy the new caps. Hopefully I will get the tanks this week and perform the installation this weekend. The stock tanks won't take you very far at all unless you're really easy on the throtle. I tried carrying 5 gal. jugs strapped behind the RPS but with heat expansion and motion on the boat fuel starts leaking through the cap making a mess (not to mention being dangerous).

Oh! I just thought of something else. What did you use to fill in the holes for the hardware location with the stock tanks? The guy at the boat yard said that 3M 3200 would be okay but I'm not sure if I should use something tougher.


Maximus posted 06-02-2004 11:43 AM ET (US)     Profile for Maximus  Send Email to Maximus     
3M 5200 to fill the holes.
seasicknes posted 06-02-2004 12:49 PM ET (US)     Profile for seasicknes    
3M-5200 works well. Just make sure you let it dry for a while like 3 to 4 days.


jimh posted 06-02-2004 08:59 PM ET (US)     Profile for jimh  Send Email to jimh     
3M-5200 is an adhesive. You ought to use a thickened resin to fill the holes. Try MarineTEX or similar epoxy resin, or just some generic polyester resin. Tint to match the deck gelcoat white color.

An alternative is just to fill existing small holes with a nice stainless steel self-tapping screw and finish washer.

I also think the dual 12-gallon tank option is preferable to a single larger tank. The best price on a plastic tank seems to be at Bass Pro Shops, were a certain model of Tempo 12-gallon tank is often sold for $50, without any fuel fittings. If you outfit the tank properly, you can change from one tank to another and use a single hose and primer set-up.

Having dual tanks is better in my opinion. If you want to run a tank of Quick-Kleen through the engine or try some other additives, it is much easier to work with a 12-gallon tank than a 24-gallon tank.

Actually, the Tempo 13 gal. tanks from Bass Pro Shops are cheaper than that. Here's my total bill up to now:

2 Tempo 13 Gal. Tanks: $39.99 ea.
2 Quick Connectors Mercury (Male): $6.99 ea.
Shipping & Handling: $8.95
Grand Total $102.91

I picked up the gas caps at my local True Value hardware store this morning (Home Depot about 1/2 hour away). I'm not sure how much they were but they were probably a few dollars each. I plan to use the factory hardware and just relocate it and use bungee cords to hold the tanks down.

Compared to $400 this option is a lot cheaper and I can still use my old tanks as reserves.

Here is another excellent article on the Pate tank installation:

For filling in old, non-used holes in Whaler NON-SKID, I recommend the following for a really professionally looking result, as caulking and gelcoat are hard to do in the non-skid and look lousy.

Buy the same size screw in SS phillips flat head, 3/4" length. The intention is to seat this screw, flush with the floor, with a little clear polysulfide cauking under the head to prevent water absorbsion into the wood underneath. Drill out the hole the exact same diameter as the screw head, just deep enough so the screw seats perfectly flush.

These exposed screw heads in the floor look like some factory detail, and nobody will be the wiser. After all, exposed screw heads are how the gas tank covers are done in the larger models.

I upgraded to the Pate 24 gallon tank. Im glad I did. The extra capacity is nice plus the see through gas gauge is awesome.
