I found this on ebay this morning. I wasn't sure if it even was a Whaler at first glance. Someone went to a lot of trouble to convert this to a "corvette boat". After looking at the photo for a while, it sort of reminds me of a Temptation or Tempest (not sure of the designation). Check it out, and tell me if it really is a 15ft. Whaler.

I don't think they went to any trouble at all, it's a Mischief model produced briefly in the late 80's. It was understandably unpopular.

My god, the thing has a 100 hp motor! While I'm no JB Cornwell, even I would be scared to run that thing. I always thought the 15 was absolutely a rocket with a 70 hp, cant imagine what it's like with 100.

But it has "nice cruising at 30 mph"......

There used to be one of these around Pleasant Bay on Cape Cod. It's actually a neat little ski boat (if you like that sort of thing) based on the classic 15 hull. I always liked the red gelcoat, and it sure beats the "Rage".

I apologize for my naivety. I have never seen one of these. On top of that, it seems the color is also a factory thing. I'm astounded. I really thought it was a custom job.

Holy cow, the thing must fly! Oddly though, there is another 15 on ebay with a 90 Yam. and the owner states 53mph top speed, I would think with a 70, the boat would top out around 45-47. Just seems like 20 more HP would push the boat up closer to 60 (wow thats scary!) Actually, that whole boat is scary, with the steering wheel horizontal like that, Oh, and look, one pull on the toggle you get lights, and second pull you get the bilge pump, wouldn't that mean the lights had to be on whenever the pump was on? Wouldn't two switches have made more sense?

Hauptjm.....don't appologise for your naivete' I had no idea either !! When is someone going to publish a big coffee table book on the history and configurations of the Whaler?

Well, you could mount your monitor face up in a glass topped coffee table, set the URL to the ContinuousWave Site, and put a mouse on the table....

The red 15' "Mischief" model was only made in 1988, as a Whaler 30th anniversary model (they also made it desert tan for 2 years, I think). They are quite rare, and this one looks to be in excellent condition. It was kind of a little "speedboat" version of a Whaler.

But as mentioned, they are a pretty disfunctional model of the 15, although I'd take one over a "Rage" anyday. They were designed by the person brought in to design the Temptation models. Note the similarity in shape.

JimH, I would grab one of those photos for the reference section.

2 things: I always liked the Mischief, it is different and cool looking but like everyone said, nonfunctional. That thing must cook with a 100 on it but it is considerably heavier than a regular 15 so it might not be that quick. 2: That other 15 is full of BS. He says it runs 53mph with a yamaha 90 swinging a 17" SS prop. Well my 90 swings a 17" SS prop and I get maybe 43. So unless he is running 6500 rpm's on a 5500 motor(which is where I run) he can't do 53.

There is another one of these up on Lake Charlevoix in Michigan. I saw it for sale at a marina in Boyne City for an asking price of $ 7500. Also had a fairly good sized mercury outboard but I don't remember the horsepower.

I almost bought one (Mischief) prior to my 15 Striper. I showed it to my wife along with my oldest daughter. They both agreed that our Striper is more practical. The daughters loved to lie down on the front cushion (Tim's I might add) and watch the water fly by. BTW, my 15 with a 2001 Tohatsu 70hp and SS prop "only" managed a max of 38mph as I recall. My "dark" season officially begins this weekend when we move the beast to winter storage in South Haven Michigan. (PS... I still think the Mischief is neat, unpractical, but neat. And I would not let my daughters near a 100hp version, without my direct supervision of course).


Bigshot posted 11-15-2001 04:12 PM ET (US)     Profile for Bigshot  Send Email to Bigshot     
Is that 38 GPS or speedo. If GPS then start messin with props, etc because a 50 will push it 38.

I agree that there is something definatly wrong with a brand new 2001 tohatsu at recommended rpms (if so) with an SS prop running only 38mph. I would be very disappointed. Hopefully its not burning the same amount of fuel as a Johnson 70hp running at 45-47mph.
I think you should find out why only 38mph. Try to find other 15'whaler owners that also have nissan/tohatsu outboards ands see whats there top speed. Just a suggestion.-EasyE

I have a 1980 or 81 catolog (Black with Red Lettering) that states both single and dual engine performance according to Whaler. I believe this was the last time whaler published this info in a catolog.

Anyway, it shows a 15 w/a 50/55 should do about 34, w/a 70/75 it should do 42. At the time the fastest boat listed was an Outrage 22 with single 235 or twin 115s, both should do 53 (so it says)

SuburbanBoy, I agree with Bigshot, your boat should do close to 45 mph. Are you sure your GPS isn't calibrated in knots? 38 knots = 43.7 mph which sounds more like it. My 1979 15-Striper would do well into the low 40's with its 1979 Johnson 70 hp (Non-propshaft rated). I would expect a modern (propshaft rated) 70 to do better than that.
Bigshot posted 11-16-2001 08:52 AM ET (US)     Profile for Bigshot  Send Email to Bigshot     
Engines were not propshaft rated so subtract 10-15%. Plus if they say it will do 34 and it does 32 the dealer is in trouble so underestimate the speed. Tell you what though, 53 for a fishing boat was like massive back in 1980.

I have a buddy with a red Mischief that sports a Mercury 140hp in-line six. There is nothing disfunctional about this boat at all. Extremely fast and the hull can take it. He uses it to comute in S.F. Bay. Belive me when I say he beats the traffic.....The only trouble that he has had is with the red gelcoat. Constantly fading and won`t hold a polish and wax. Steve out.

Steve, a 15' with a 140 hp? Surely you jest! Don't tell JB. Could you snap a digital picture of his boat and send it us? I gotta' see this.

When I stated my top speed it was under the following conditions:

New motor <50 hours
4" jack plate (manually jacked up about 2")
stainless prop (4-blade x 17 pitch x 13.25 diameter, Power Tech)

4 adults
Two full gas tanks (6 + 9 gallons)
Large cooler (full)

Does this still seem slow, GPS 38mph (not knots) and ~5,800 rpm?


Tom W Clark posted 11-21-2001 12:57 PM ET (US)     Profile for Tom W Clark  Send Email to Tom W Clark     

Ah ha! Four adults and a full cooler, yes I think that explains it. Try it by yourself and see if it doesn't do 45 mph.

Not with a 17" wheel. What is redline?

Redline is around 6,000 as I recall.

Tom -

When you get a copy of the 15' with a 140 hangin' on the back, could you post it? I think we're all a little curious to see that.

It seems no matter what topic I read on this site, someone feels they must bash the Rage. Does your 15' self bail, will it run wide open in 9" of water, I dont think so. Do I worry about losing a prop or lower unit or the kids getting hit by a prop, no I dont. It has to be the safest boat made and to me that says it all. Opinions are great if they are constructive, but without knowledge they are simply malicious gossip.

My 15 classic would self bail and run close to 50mph in about 9-10". Never bashed a Rage but answering your question.

Hey guys, I owned a tan one and a red one! The tan had a 70hp 3 cyl OMC... Evinrude and the red had a 71 cubic inch 3 cyl merc. Nice details but I never really liked them very much... the flat deck made a decent casting platform however. As to performance, if I can recall correctly, the tan would hit 45mph and the red 50mph. Handling was supurbe and the extra weight fwd helped the high speed stability. The Mischief came with a clever baording ladder on the port side and they had tilt steering wheel.. It was a love em' or hate 'em thing and dealers had a hard time selling them.. BTW, speeds above were clocked by a car speedo. running on road beside boat. We had no good speedos or GPS in those days... Nice to remember some of the really different Whalers... Wouldn't want another, however! Happy Whalin'.. Clark.. Spruce Creek Navy
