What kind of range do you all get with the 77gal fuel tank found in the 22OR ? I'm considering adding an under seat aux. tank for safety. My experiance with the fuel gauge on OR's is that a 15-20% error can occur when the fuel gets below 1/2/full.
(I run a pair of 135 merc, carb)

There has been a general consensus that the 22 Outrage could often use more than the 77 gal tank. There was an optional 129 gallon tank option, but it tended to make the boat very stern heavy, since all remaining gas ended up down in the stern of the tank/boat.

I occasionally use my 18 Outrage with auxillary Montauk style tank(s) under the Reversible Pilot Seat. Whaler's own advertizing used to recommend this setup for extended range. So if you have the RPS, or a leaning post with a space for a cooler, this could work for you.

You can use either a single 27 gallon Tempo/Moeller tank, or twin 13 gallon tanks by Tempo. Before buying either style, decide how you would actually use this reserve fuel, especially if you have twin engines.
The issues are:

1. Do you want to run one or two engines on the reserve? Do you want to carry one or two extra fuel lines?

2. Once above is decided, will the extended range fuel be used first, or last?

My answers are these: Use the reserve fuel last, so you will know EXACTLY how much you have left. This means you will first run the boat tank dry, then plug in the two reserve lines, one to each engine. This probably means you buy the two 13 gallon tanks rather than the big single, or get a two way valve for the 27 gallon tank.

There are many other scenarios that could be used, especially if you want a big single tank. If your boat is single engine, the single tank makes the most sense, but is heavy to handle if it has to be removed before being emptied.

Every Whaler with the mechanical fuel guage should have it's fuel gauge calibrated, so you know exactly what you have left. With boat in the water, run the belly tank dry.
Then fill boat, IN THE WATER, writing down the gallons taken as the gauge hits EACH gradation. Make a little chart for yourself, and you will know exactly how much gas is left in your tank, with boat at REST.

For what it's worth-My 23" laguna had twin 135 Mercs w/carbs (1988's). Carried 120 gallons of fuel,and the Seray weighed 1400 # more than the Outrage. Running 60 miles out, troll for 4 hours, 60 miles in on fumes.
Those mercs were thirsty...

I have a 22' OR...with twin Evin. 88 SPL's. We typically run 130+ miles round trip fishing burning around 80 gals. I have the 77 gal. tank, a 24 under the LP, and a 26 Moeller that I just sit on the floor. I run a line from each aux. tank to the filter/sep. running out, then switch to the floor tank to fish,this works very well.The floor tank gets moved up front when empty.

Might be worth the $160 investment in a fuel flow meter. I talked with the guys at the Navman display at the Miami show. They said it uses a standard 3/8" (10mm) fuel line. Depending on how your setup works, one or two of these gauges well placed could improve your estmimated fuel remaining, and the optimal speed for economy cruising. Range is a variable that depends alot on how the boat is loaded, trimmed, and what speed you run.

Then again, the same $$$ put toward additional external tanks allows you to run the built-in tank dry and know your true range on 77 gallons.

Larry are you saying that if you were in the market for a 22, that you should steer away from one with a 129 gal tank. Keeping in mind if I were looking for a 22, one requirement would be that it have twins which is already a little extra weight by itself. I would like to hear the opinion of 22 owners with the larger tanks also.

On my 22' OR the 24 gal stays under the LP, the 26 gets moved when empty. For the ride out (30+ miles) the boat is noticably stern heavy. This is with twins (288lbs ea.) Given my experience with that, it seems the fuel would always be further back with the big floor tank making those boats stern heavy all the time. I think the ideal situation is to have the fuel economy and not need all the extra fuel!

Tom Byrum,
We have the 129 gal. tank in DIVE 1. The good thing about the tank is the extra capacity-our 155s drink like crazy. The down side is the added weight. Also the rear tank vent leaks fuel with the gas tank full and on a steep launching ramp(you must think ahead). All things considered, the big tank works well for us. We have come home on fumes after being on a call for only 3 hours. A normal call averages 6 hours and we usually come home with 1/2-3/4 tank of fuel. If we get in late, there is no place open to get fuel. Inevitably we will probably get another call that same night and having fuel in the boat is a life saver.

Tom B - I think Jim's Guardian has an exception to the HP rating with twin 155's, which probably is why the big tank went in.

But from what I have heard from a fellow who has a 22 with the big tank, and twin 115 Mercs, he doesn't like the water he gets over the transom quite often. The big tank uses up the space from the stern baitwell. he says all remaining fuel is always in the stern becasue of running attitude, plus two batteries, etc. A lot of weight back there.

If it were me, and large twins were in the picture, I would get a 22 with the standard tank, and carry a pair of 13's under the RPS if necessary. This would get the weight forward also. Or find a Whaler Drive model with the large tank. My guess is that would be a better solution.

On my 22 OR w/WD and a 250 Yamaha after a rain, that bait well would be full of water. I think this would simulate the big gas tank. The transom would be about 2-3 inches lower, and the top deck of the WD would only be about 2" abouve the water. Plus, a few times I went out with the bait well full of water and there was a VERY noticiable ammount of time added to the hole shot.

Thanks guys, after seeing your reply's and visiting other 22 set up's, I have decided to add the extra fuel in a tank forward of the console. Additionally I am moving the batteries into the console.
Everyone seem to agree that this boat is tail heavy, even with the whaler drive,and that moving weight forward is the best solution to balance and fuel economy.
Gracias, Jim

Please allow me to digress a bit: where can you find a flowmeter for $160? I thought they started about $299. I have seen another brand of fuel flow gauge for $229 in the Boater's World catalog.

Just one more note about range on my 22. I would go fishing with another guy and all of the equipment for deep trolling for Salmon. With a full tank, we would head out @ 4300 rpm for about 15 miles then troll with that big 250 Yamaha for about 3-4 hrs, then back again and use about 25 gallons.

I have a 22 or w 1999 yamaha 225 and 77gal tank. I go 55 miles Miami-Bimini on less than half tank. I have flow meter, figures max of 3 miles/gal. Meter is dead-on when it comes to gas used. Never off by more than 1/2 gal out of 77. I'd get the flow meter, leave out the messy gas tank, and save valuable space.
If I did get a tank, I'd replace the front cooler as a seat for weight distribution and space.

Larimore...what prop, mounting hole location, whaler drive (or not) is on your boat??? I'm repowering with a Yam 225 and would appreciate any info...Thanks!!

Standard-Horizon Fuel Flow meter $198. http://www.consumersmarine.com/products2/flowmeters.cfm?menu=instru&banner=009999

Navman Fuel Flow meter runs $50 cheaper, since Navman makes Standard-Horizon's. I can't recall where I found it, but I'll keep looking... I know it was in one of the recent issue catalogs.

Navman Fuel-Flow meter. Boaters World. $150

Now if someone with $150 would go buy one and test it for us, that would be great.
