I've been thinking about a new project this spring if one comes along. I currently have a 12 foot john boat that I would like to use the engine and trailer from if possible.
I have a 2002 8hp Mercury 15" shaft 2 stroke- will this be enough to plane and the right length shaft for the transom? I also have a 2001/2? Magic-tilt john boat trailer for up to 13ft. not sure how many lbs rated but guess I can probaly rebunk for Whaler hull? I would even consider a 9foot? if one were found. Just something to mess around with and take to some of the small lakes around that are too much with my Dauntless.
Still in the "what if" stage but you never know.

Thanks
Chris

I think that 8hp will just barely plane off an 11 fter with a light person. I would go with a 9 fter if it will just be you in the boat, it will be fun to have personnel rocket ship.

In my experience an 11' Standard is harder to plane than a 13' Sport. I have planed both with a 9.9, but never tried an 8.

The 13' planed easier than the 11' with the 9.9 Johnny 4 stroke, but neither planed easily.

I doubt that an 8hp would do the job.

The 9" is a displacement hull and would be even harder to plane, not to mention being overpowererd with an 8.

RyanWhaler (formerly known as "11 Footer") has experience with the 11 Sport and an 8hp. Let's see what he has to say.

I had a 1987 8 hp Merc(older, but same as yours) on my Sport-11.

Depending on what your using the boat for, it may be okay but it most cases it will be underpowered. I was able to get it on plane with a light load, gas tank up front and about 130 pounds in the stern. Unless your talking about small children, its a one man rig.

I found a new old stock 1990 15 hp Merc and bought it, the 15 is the same as the 8, only difference is a bigger carb. I'm happy with the 15, in most cases it will plane the boat out with normal load, but its slow out of the hole best I ever got out of it was just over 21mph, on an eleven foot boat with just inches for freeboard, that's plenty.

If you already have the 8 hp, I'd look into swapping the carb out for the bigger 15 hp carb. I still have my 8 hp Merc and the ONLY difference between the 8 hp and the 15 hp is the size of the carburetor.

If you haven't bought the boat yet, I'd look for a sport model over the standard, it moves more weight forward, helping the boat get on plane. I ran my 15 hp with a tiller a few times before getting the controls rigged up, the remote steering makes a big difference.

See my eleven w/15hp here:

Chris, my neighbor has an 11' with a 9.9 Johnson on it. It's a bit of a dog getting up on plane but will with two people in it and you have some time. Don't expect it to save you from the rapids or waterfall just downstream. My 11' has a Merc 20 on it. It flies like the wind. Both of them are tiller steered. Get the boat, use the 8hp for a while, buy my 20 and I'll go get myself a 15 hp 4 stroke.

I have been able to get my 9fter up on a plane with a 9.9hp Evinrude (mid 80s) and it runs great once on top. It would not plane with two adults but with one person it was alot of fun. I have seen a 9ft Boston Whaler with a 25hp Mercury and the guy would run it across a pretty big bay. As far as modifying your 8hp, it is not an option. The 6hp is the same as the 8hp. The 9.9hp and the 15hp are also the same but are different from the 6hp-8hp motor. Just my 2 cents

I have both a 8hp and 15hp and have looked at them next to eachother, they ARE the same, the gears and exaust are even the same. The only difference is the carb and I can be switched.

Chris, Not to disagree with the punk , but your 8 is not the same as a 15.( different displacement, bore, stroke and weight)

We have an 8 yamaha that we use on our 10'rib inflatable (110lbs) and it will plane with one person and once on plane is plenty fast.

It will not plane with two on board and with the whaler being a few pounds heavier , wider and longer I don't believe the 8 would work well on an 11' whaler.

So get the whaler then tell your wife the 8 will not work and then your forced to get the 15hp and everybody is happy.

Merry Christmas and Happy New Year

post the question about the difference between the two merc. engines to iboats.com in the forum section for mercury engines. The people are extremely knowledgeable.

11" Power
I owned an 11' tiller model for several years. Great little boat. The max hp rating is 10 for the tiller model and 20 for the console model. My tiller model was powered with a 15 hp Johnson, which is above the rated max, however it handled the hp just fine. It could easily hop onto plane with 3 adults aboard. I do not know how it would perform with a 10 hp. I hope this helps.

As I said before, The 8hp is the same as the 6hp and can not be modified to be a 9.9hp or a 15hp. The 8hp is a different engine from the 15hp and the 9.9hp. They look close but they are different motors.

If you wont take my word for it, please take Mercury's!

Captbone is right except for ryan's 8 and 15 cause he looked at them.

My 8 hp is a 1987 and my 15 is a 1990, and I've been told by an outboard shop that a different carb would make it a 15, maybe this hemroid is right about the new ones, but mine are the same

You asked for that 2Many. Troll for Ryan and you will get a hit.

What do you expect when you offer unprovoked insults?

I used to have a '63 Impala SS with a 283 c.i. V8 and a 2 barrel carb. It was rated at 195 horsepower from the factory. I put a big Carter 4 barrel on it, and right away that little 283 was putting out 375 horsepower, and I was blowing the doors off of big block Corvettes...now if you beleive that story, I've got another one about a little outboard motor...

The displacement on the 15 h.p. is 262 cc, and on the 8 h.p. it's only 210 cc. If it was possible to get 87.5% more horsepower just by changing the carburator, that would be a neat trick. From a manufacturing standpoint, it makes sense to share components like lower unit housings, gear cases and shrouds among several different motors, because these things require lots of tooling to produce. Just because it looks the same, it doesn't mean it is.

By the way, when I changed the cam, heads and exhaust on that 283, I got noticablby more power out of her, but I'm sure it was no where near the 300 h.p. that the 327s produced right off the showroom floor. Remember, there's no replacement for displacement ;)

Or, as an old high school buddy of mine (whom I envied because he had a new '64 Chevy Impala SS with a 409 and 4 on the floor *while in high school*) used to say, "You can't beat cubic inches with a stick". Great double entendré, and appropo.

Thanks for all the replies. Still dreaming and if the right one comes along may go for it. I may be wrong but aren't the newer 15 hp Mercs 3 cylinders versus 2 cylinders on my 8hp? Maybe I'll fire up my 7.5 hp Gamefisher and run twins! (1 cylinder Tecumseh 2 stroke circa 1977)

JB , I don't think I said any of what ryan has said made my mad at all, its way funnier than insulting.

If you know what your after and use the right bait properly presented it changes from fishing to catching.

Well, you may find it entertaining, 2Many.

I don't, and I don't think trolling for a fight has any place here.

That sort of juvenile bullying and bickering drove me away from this site once, and it has driven away many better men than I.

Please knock it off.

Merry Christmas. :)

John,
Back then, a 425 h.p. 409 was something I daydreamed about often. 3 For reliability, the 283 was hard to beat. That motor didn't owe me anything, and was still running strong with 175k on the original bottom end when I sold her. One of these days, when I've got my Outrage just the way I want her, I'm going to find a nice '63 SS ragtop and build another one.

Ryan, the 8 and the 15 are not the same except for different carbs. Theres no way, the displacement, bore, and stroke are all different, they may look the same from the outside, but inside, they are very different. If oyu dont beleive me try puttin the carb off your 15 on your 8 and see what happens.

Just curious about what would prompt an adult(?) to go after a kid, not old enough to drive, for kicks? Does this pass for entertainment where you live in Miss.?

You then wish everybody a Merry Christmas. So much for the spirit of Christmas.

It's really tiring to go to this site looking for information about BWs and have to be presented with this sort of thing. Please think about what you're doing. A previous post has commented about leaving because of this. There probably have been other people who were disgusted and didn't even bother to post before they left.

Ryanwhaler: It may be tough, but how about being mature enough not to respond to an obvious troll like this? People here have had many examples of how you respond, and sometimes it's not pretty. You seem to enjoy the site, how about making it enjoyable for others who are not here for a brawl?

I'm on a few other motorcycle and vintage car sites and have never seen anything like the rancor and viciousness I see here at times, and unfortunately it's not just limited to the two participants here.

I grew up in the Bronx and worked as a peace officer for many years. I'm not afraid of a fight, I just don't think this is the proper venue.

Maybe if some others also let some of these people know how you feel, either publicly or privately, this sort of thing would stop before we lose other members.

Sorry for the rant, Steve

Speedo , If you look at this thread closely you will see that I called ryan a punk and asked about reform school.

While I not sure about the reform school , I am sure he is a punk both here and at one other site for sure. In return I have been called white trash , jobless , a homo with chess playing fag friends, a himroid ?, all of which are not true, ryan has also claimed that my sister pays him and his friend for sex so they can buy boats.

So when ryan stops giving advice on things he knows nothing or very little about and gets to to the point were he can #1 take a joke and #2 respond to people who disagree with him without the foul mouth, he will not be a punk anymore, I will not call him a punk anymore and all will be right if not in the real world at least in this virtual world.

Love , peace , Merry Christmas and Happy New Year

ps, as for kicks in Miss. we just ride around in our trucks and throw beer cans out the windows and shoot our guns up in the air .

Why you do some of you all have to be firing on each other? This site should be about fun and Whalers. I think the war has got everyone churned up and touchy - esp young folk.

ON THE SUBJECT! - We love our 11.5 and I messed w/ 9.9 and agonized over proper HP for months. I got a 25 Johnson, tiller w/ electric start and as far as I'm concerned it's just right for the boat. It makes the boat fly if I want it to, hauls a load if I want it to, trolls pretty well and I never use the electric start - pulls "on" just fine. I can run the sucker at 1/2 throttle and stay on plane w/ passengers and if I need to throttle up and scoot, away we go - right now!

I am, however, strongly considering converting to console steering - salvaged a proper mahogany console from a 13. ANy thoughts Whaler bros?

Moving the battery and fuel forward helps static trim and allows the boat to be self-bailing when no one is in it.
