there is a sticker on ours that says that you must remove the center support if you want to mount one engine.

Actually, they were DESIGNED for twin 25" shaft length counter rotating twins. Without Whaler Drive, none of the Outrage series boats could handle this new technology (they were designed for 20" twins), offered at a minimum of 150HP, in 1987 without transom jacks, so this was the solution. And it increased the HP ratings on the 20's and 22's so that the 300 needed HP could be accomodated.

There is not one single catalog picture showing any size WD model with a single, nor are there any specs showing a single. All the specs indicate twin 25" shaft engines as recommended power.

But evidently the Dealer network quickly complained that a pair of 150HP CR twins raised the selling threshold too high, particularly on the 20's and 22's, so as mentioned they allowed them to "unrig" the center tie bar and install a single. But top speed suffered considerably, because of the additional drag and weight, the boats really did need more HP than 225, whereas 225 on a notched transom 22 is about 6 mph faster (42 vs 48).

I have never seen a WD 25' hull with a big single, however. They definitely need twins, usually 200's or 225's.

The minimium HP information you gave was for a 25, correct? Have you seen a WD 22' with a single? I have not, but always assumed that it was possible, although I too have no idea who would want to do it.

Can you use one big out board on a 22 foot revenge.also if you had a choice would you prefer a wd or not. it seems to me that the two engine requirement for a whaler drive would not be prefered by most thanks ron

Witness - What I meant is that the outboard manufacturers, Merc, OMC and Yamaha, only offered 25" V-6 CR twins as low as 150HP engines. So even a 20' Outrage or Revenge WD was rated for 300HP.

In a recent Cetacea page, JimH has posted a picture of "Outrageman's" recently sold 22 Outrage WD ("Doghouse") with a Yamaha 225 single. An exceptionally nice boat, and very nice to drive, but I would have loved it with a pair of "Qbrennan's" 150HP Optimax's on it!!

Ron, because I have a full transom Whaler, having made that decision, I am biased, so I definitely prefer a full transom 20-25 model.
I think it makes for a very nice Whaler, with either a single or twins.

There is a 25' outrage rigged with a single in Florida.

George-Ron There is a 22' OR cuddy for sale at Sunrise Marina at Port Canaveral with Whaler Drive and a single. 89 boat with 225 older Johnson. Ask $18,500. Boat just looks too heavy to reallly booogy with a 225. Needs some TLC. FYI and my opinion. David

Yes, it WAS a fun boat to dirve - sniff :(

But it had a Yamaha 250 on the back of it...

Hey Whaler Drive guys; I'm working on a 22'OR w/ WD and dual 135 merc's of the 1990 vintage. They came without props, so I need to add S/S. The mercury prop selector tells me to use 23" offshore series and in some cases, were I use a hull length of 24', to use 27 -30" pitch. These seem high to me, but I have no experiance.
What are you all using in a W/D set up ?
Thanks, Jim

That does seem awfull high to me.

Granted I ran a single, but I had a 17" Merc Mirage Plus on the boat. The Yamaha 250 gave 43 (gps) mph at 5400 rpm.

JAC - My older (1995) Merc prop charts indicate 21" props for your situation, with a speed range of 44-50MPH. If the engines are in good shape, you should get the 50MPH. If you think the boat will do over 50, then you should use the 23's, but I would think that would only apply with a light load. I would recommend the Counter rotating Laser II props, and be sure the engines are mounted in the 3rd or 4th bolt holes up on the Whaler Drive. You'll probably want to run the vent holes plugged, since you'll have plenty of torque for acceleration, and don't want the slippage at slower planing speeds or lugging along in rough seas. Those are 2.0 liter (110 Cu. In.) engines, at 2:1 gear ratio. Seems like an excellent power choice for a 22 Outrage WD.

The current 135 Opti's are using the 2.5 liter block of the standard 2 stroke Merc 200's.

Thanks Ihg, based on your info I've found a pair of 21" laserII props to tryout. I'll move the motors up on the W/D as you suggested and give them a spin.
I don't have CR, so I expect some pull. I'm looking into a set of CR gears to rebuild my lower unit. The cost of a rebuilt CR lower unit was too high to justify. A friend will do the rebuild for a small sum if I can buy the gears right.
Thanks for your insite, Jim

I have a 88 22'Revenge that I purchased in 97 w/T120 Johnsons. Motors and boat ran great w/one problem. The boat irated for 240hp, the twins combinedweight was appr. 700lbs. Drifting in rips or fast current was impossible. Whaler would drift transom first and constantly take wate on. On a tip to whaler, we found a old timer, not Dougherty, who said there was a spray guard made to deflect the wash into the well and out. He gave us a copy of the plans which I still have and will send to anyone interested. The cost originally was about $1000.00, but not correct the drift problem. The correction was a single motor and all was well.
