Author Topic:   Outrage 18 with 200 HP: Over-Powered; Transom Integrity

boatdryver posted 01-19-2006 08:07 PM ET (US)
[The author is seeking advice about potential purchase of an OUTRAGE 18 with a 200-HP motor.] I was disappointed to hear it has a motor this large. I don't know which brand of outboard. [The author seeks] tips on evaluating the integrity of the transom. With a 200-HP, should one infer the boat was run wide-opem-throttle a lot for skiing? Thanks, Jim

The 200 on that boat means nothing. Don't worry about it.
LHG posted 01-19-2006 08:35 PM ET (US)
Most should be so lucky as to actually find one with a good 200!
jimh posted 01-19-2006 10:35 PM ET (US)
A simple test of the condition of the transom may be conducted by tilting the motor up, holding the end of the skeg, and moving the motor slightly. This will give you a long lever arm on the mounting point. If the transom flexes under this load, it is an indication of lack or rigidity.

You could have a problem insuring it.
Off hand I don't know the maximum rated hp for that particular boat, but I don't think it's 200.
A 200 should make that boat perform awsome.
Hey, just remember, you don't have to use all 200 horses all the time, & when you need em, their gonna be there big time & your gonna love every one of em.
I don't know what kind of speed your gonna get but I'd say 60ish.
Just make sure she's propped right to turn maximum revs & mounted up on at "least" the 2nd set of holes.

I know everyone thinks you can't have too much, but I would be concerned about safety problems popping the throttle with that much power - and leading to loss of control.

My friend has a 200HP Mercury on his 1984 Outrage 18 and the combination works great. I wouldn't worry about it at all.

What is the posted max HP?
Tom W Clark posted 01-20-2006 02:25 PM ET (US)
The Outrage 18 is rated for a maximum of 150 hp. 200 hp is hardly unusual.
prj posted 01-20-2006 02:26 PM ET (US)
Depends on which model year.
The Classics have a max. HP of 150.
I wouldn't be surprised if the larger and heavier
Post Classic 18' Outrage has a 200 HP max.

Jim is looking at a 1991 Outrage-18 with a 1991 Yamaha 2-stroke oil injected engine (L200TXRP I think) with unknown hours.
LHG posted 01-20-2006 03:24 PM ET (US)
For some reason, I'm with Sal.
Didn't someone here once calculate that the 18 Outrage actually could be rated for 180HP under the BIA rules, and the BW arbitrarily downgraded the rating? Kind of like the 170 Montauk.
There are, however, three 200 HP engines that I would not put on this boat. The 3.0 liter 200 Optimax, the 3.3 liter 200 Evinrude, and the 200 Verado could be a bit much! I would stay with a 2.5 liter version.
Buckda posted 01-20-2006 04:02 PM ET (US)
The Federal guidelines allow for 170 HP (172 rounded to the nearest "5"), however that is without running the course prescribed in the code of federal regulations. Perhaps the running of that course and the results are what caused Whaler to downgrade the rating to 150, or perhaps, since they could not round up to 175, and the next lowest HP was generally 150. Plus, for twins, you had the option of 180 HP (Twin 90's) or 150 HP (twin 75's).
That said, I think we all know that the boat can handle both more weight in the stern than the currently stated 427 lbs, and can handle more power than the rated 150 horses.
prj posted 01-20-2006 04:19 PM ET (US)
Furthermore, doesn't that 1991 Outrage -19
have the additional liner, adding about 5-600 pounds?
Go for it, I say.
boatdryver posted 01-21-2006 11:11 AM ET (US)
According to the reference section, the new liner which resulted in a glassed- in and essentially inaccessible fuel tank started in 1992 with the Ourtrage 18-19 hull.
Can some one confirm this? I would not want this setup on an older boat myself.

Patrick,
It depends. Some of the last of the Outrage 18/19s and the early Outrage 19 IIs were built concurrently. The boat Jim is looking at could be either but I suspect the former. A few descriptive details or a photo will tell.
taypow1 posted 01-21-2006 12:14 PM ET (US)
I have a 1992 Outrage ll and would love to have a 200 HP outboard.
I don't think it would cause any problems at all.
Like Sal said you only need to use all 200 horses when you want to.

I ran a 1992 19ft Whaler (18ft 6) with a 200 Evinrude after upgrading from a 175. The boat was stern heavy, something that could be avoided with the new 200 E tec, but the major issue was the transom. After 10 hours of use there were cracks in the Gelcoat between the mounting holes and it was clear that a combination of weight/power/torque was simply too much.It also resulted in a slight trim problem.
I dont know how long he has had it mounted, but I would be wary given the max rating is 150 and as it is not a new etec, must exceed the weight limit.
LHG posted 01-21-2006 06:28 PM ET (US)
The above comments from pineapple are brand specific, since OMC never made a 2.5/2.6 liter 200 HP engine like Mercury and Yamaha did in the early 90's, instead building it on the 3.0 liter block. For those brands, the 150 and 200's are identical, same weight, displacement, etc., and would not cause the problems he is indicating.
Tom W Clark posted 01-21-2006 07:01 PM ET (US)
Pig's comments don't make any sense at all. The biggest OMC 200 weighed 455 with the 25 shaft. I had more than that on my Outrage 18 with its 150 and 9.9 kicker not to mention the dual batteries. Not a weight issue at all.
As to the cracks, it has nothing to do with horsepower. It is was probably the result of over torquing the mounting bolts when the newer motor was installed.
Teak Oil posted 01-22-2006 12:04 PM ET (US)
Since Larry's transom has lived 20 years will well over 600# and 230hp on it, I would tend to think the Outrage transom can easily handle a single 200 for a LONG time
crashq posted 01-28-2006 04:03 AM ET (US)
LHG I thought I remember that when they first came out with the Outrage 18 that it was supposed to be rated for 175, but for some reason like its classification, they lowered the rating on purpose.
crashq posted 01-28-2006 04:05 AM ET (US)
That thing must scream. Mine will do 48mph with a 140 (V-4). I can't imagine another 60hp. You could see 55+mph
