Author Topic:   High performance Whalers?

With all the talk of overpowering a Whaler etc and boats like Larry's, does anyone here have a "High-perf" Whaler. By High-perf I mean is anyone running a high perf engine such as the 150-300hp Merc/Mariner Pro-max engines. Mercury offers and has for some time a 150-250hp higher performance engine that is not radical like the 2.4-2.5 offshore 7500rpm screamers. These engines are under the pro-max or Optimax XS name. They are more potent than the XRI etc but more like a 62-6800 redline with a better gearcase, etc. OMC also made some whacky engines like the 45ss and the Formula E, anyone run one? A guy by me has a 21' Mako type with a 2.5EFI on it, sounds like it could SCARE some fish and some occupants. Just wondering who besides Sal and Lhg are running 55+ in their Whalers.

Nick - Believe it or not, I actually looked into those for the 25, and quickly took a pass. First of all, they are very expensive, and need high octane gas.
Secondly, not too many models are offered in 25" shaft length, nor with CR, except for the offshore racing type. With the higher revs, they do not last as long, either. But I agree, they sound great.

With a Whaler, you can really get as much speed as you want without going to one of those engines. You don't even see many of them on the Bass circuits. For instance, on mine if I wanted to achieve 70+ MPH, I could simply buy out-of-the-box EFI 225's for a lot less than the Racing Division products.

Whaler's 1988 Anniversary Newsletter showed an 18 Outrage, with stock 150 Johnson, being used for Offshore Racing. I think they got 5th in the race!

In an '85 18 Outrgae with a stock '95 150 Oceanrunner and the bracket, I've hit 52 mph on a flat Louisiana bayou. I was by myself, sittin' low and measured with the GPS.

Anybody know what happened to the Jersey '83 workboat spec 18 Outrage with a 235 hung on the back? Looked fast sitting there.

I squared off against the local volunteer rescue boat when my boat was new,I was a member and had clocked their boat at 58mph with the GPS.
I got on plane quicker and never looked back so I know I was going at least that fast.My speedo on the sounder said I could go 55 knots.
That was when the boat was new and lighter.
I've added a lot of weight since then that can't easily be removed for a speed run but I can still hit low 50's.
There are lots of tourist boats here in the summer and lot's of them are pretty quick but as soon as it gets lumpy out they have to slow right down.
I still haven't seen another boat,larger or smaller, of any type, that can keep up with me when it's rough out.
I just slow down to 26-28 mph,and trim it in to keep the bow down, and it's just like a big sled, no pounding or air time.
The local CO's have a new RIB with twin 250 yamahas on it, but they won't tell me how fast it goes.
Cheers, Brian

nah, only doing 50mph in the 15' Sport. Haven't even exceeded the HP rating on the hull yet... Need larger tail to keep stern planted on the water, though... Something like the retracting one on the back of my VW Corrado would be good. Pops up at 45mph, retracts at 12mph...

Previous operator of the 25' Frontier we have at work said the pair of 225hp mercs would push it over 55mph... You need that sort of speed with a blue light on the roof.

My buddy Dunk from NJ was out last year, saw this 20' outrage coming up from behind him.
Dunk was in his converted seabird from inboard to a 235 Johnson.
He thought he would wait till he was along side the Whaler & punch it & leave the Whaler behind.
Much to his surprize, the 20' Whaler went by him like a shot & went out of sight.
He sees the Whaler tied uo at a dock & stops to see what in the world the guy was running.
He had twin 175 hp FICHTs on it.
The guy asked Dunk if he wanted a ride, it was about 2 ft chop.
The guy hit it & buried the 60 mph speedo & duck has been on fast boats before & raced himself, said they were running right around 75 mph or more.
I'v sse those fire breathing mercs on the bass boats around here, noisy as a tractor, smoking like a truck, but man are they quick especially with quickie units.
I just got my bass & walleye magazine, they show the results of testing the big three 250 hp engines, Merc, Evinrude & Yamaha.
Strange that Merc & Yamaha both switched from EFI to DFI.
Merc also has a 1.65.1 lower unit for them for racing.
Merc pretty well ruled it but was running a laser tuned $1,125 prop compared to stock off the shelf props on the Evinrude & Yamaha.
Back to your question, nope, never seen one on a Whaler.

Saw a 17' Montauk running fast with a 135Hp v6 evinrude the other day. Sits low in the stern but runs fast!

The 135 hp is a "V" 4, not 6.

Sallie....again you disappoint me with your misinformation(in my best Godfather impersonation).

The 135 Evinrude is a V6 ficht. The last V4 135 was back in 1976 which weighed under 300lbs so it would not sit low in the water, nor be that fast according to you because it is 27 years old. OMC did make a 130hp looper when they dropped the 120 & 140 and just made the 130 which was a 2.0 litre and basically a half of a v8.

Had a brain fart, thinking of the 140 crossflow.

Those OMC V4 140 crossflows actually weigh more than the v6 175 60degree Johnrudes.

I gotta tell you, those 140 crossflows were some darn hot engines for a 4 banger.

Gotta love the bubblebacks! (140 cross flows), The OMC gurus have gotten serious horsepower out of the little V-4 mill. Using some off the shelf OMC parts(earlier carbs), porting and aftermarket reeds I have heard of 160+ hp. Maybe somebody will mount one on a Montauk and report some numbers.

Are you talking croos flows or Loopers? The cross flow 140 weighs the same as a 90hp. The looper 140 which is a 2.0L block and V6 lower unit is about 365lbs or so.

I see numerous references in various threads to Whalers with engines above their max rating. Are these owners who buy the engines separate, mount them at home, and don't have insurance? I asked a local marina about mounting an engine over the max and he said he wouldn't do it. I didn't check with the insurance company but I can't imagine they would like it much either. Thanks

Way too many threads on this but to answer your questions....NO & No. Many mechanics will mount the engines on boats. Most insurance companies will insure you for a higher fee.
