Do you guys think a 225 HO would be to much for a stratos 275 pro xl?The boat is rated for 150hp.My motor is a 3.0l omc 225 with 145lbs comp.,tricked out big bores,yamaha ignition,etc.It should be making a good it of power.Well anyways I found a deal on this boat and I have this motor sittin around and thought it mite be a little fun!!!!or scary...fast that is.

I THINK,YOU WILL HAVE SOME HANDING ISSUE'S WITH THAT WEIGHT MOTOR,AND STILL NOT THAT MUCH SPEED WITH THAT PARTICULAR BOAT.---ED

I have a 89 285 Pro rated for 175 and run a 3.0 looper that's ported, 145 - 150 lbs compression and very strong. You will definetly have handling problems. It won't be a rocket ship but it if you can get it where you can keep it in the water and learn to drive it, it will definetly haul butt.

Handling characteristics change crastically with a heavier motor on the back. I have found that switching from a 150 2.0 to a 200 2.4 did not change the handling characteristics that much once the setup was fine tuned, but the weight variable didn't change very much. 3.0L are heavy.

Most boats can handle bigger horsepower, lots of drivers and wrong setups can't.

Oh I forgot,The late model omc 150s weight is 419lbs.My stripped down 3.0l comes in at 436lbs.Will 17lbs really make that much difference?Would you run less setback with a heavier motor?Thanks for all the help.

I thought the 3.0L were much heavier than that, what year is it?

It started life as a 2000 fitch motor.I took off all the injecton & vro crap.put on aftermarket intakes,custom heads,&Bob Kottman big bore carbs & yamaha ignition.I took off everything that I could-airbox junk etc.I put on a lite weight cowling.All that Injection crap is heavy.A stock 1987 GT 200 was 450lbs.,The stock 2000 fitch motors were 509lbs.!!!!

Blue print the hull and I think you'll be suprised at the performance. You might even want to try a 12" jackplate so the boat runs flatter with all that power.

That hull should run mid 60's with a 150 and 6" setback. At the same speed it will actually handle better with more power, of course you won't be anywhere near the same speed!

Go fot it! It should be a real hoot!

So I would want to run more setback with the bigger motor???Well Ive seen a few of these boats run 70-72 gps with 150s with the right setup.I think mid 80s+ with 250++ HP should be no problem but I geuss I wont know for sure until I try it.Look at Ronnies 15ft viper with that 280hp merc!!I bet thats over twice the rec. HP.I know its a much better hull,but still that thing ran 100+!!I dont know how that thing never blew over?!?!?!?!

Ronnie is one h##$ of a V bottom driver, thats why it never flipped over!

The Stratos is much heavier than a true performance hull of the same length, that is why I suggested the additional setback. On a light hull it might be a bad idea but IMHO I think a larger setback will help. You will be able to use less positive trim and the whole boat will lift rather than just the bow. I think mid 80's with an honest 250 hp is possible.

The reason I suggested blueprinting the hull is because those boats didn't always stay in the mold the right amount of time and some of the smaller bass boats have a hook built in the pad to aid in planing a heavy load with a small motor.

I looked into buying that exact same boat a few years ago but they wouldn't sell it to me without a motor, I was going to put a modded crossflow on it.

Thanks for the replys.Ive always have had to do stupid stuff like this.I once had a Glasstream 140 stinger bass boat(13 feet & some change)That had the bottom fixed with a hopped up Johnson SST-60.It would run 70ish with a 23 pitch Hopkins cleaver on it.I just like to be different/crazy.I think I mite just try this to see what it will do.If I dont like it I can always sell it and buy something else.....

I'm sorry but I would not use more than an 8" jack plate. Don't know what year model you 275 is but my 285 is a 1989 and bare hull weighs 1,400 lbs. I'm running an 8" plate and I will play bouncy, bouncy badly at slower speeds if you don't have it trimed all the way in. Granted for all out speed, I think a bigger plate would help lift the bow, but slow speeds would drive you nuts.

If you can get the boat tamed down enough to drive it, I have no doubt it will get well into the 80's and maybe in the 90's. My lead sled will run in the 80's when the star's, sun, moon and clouds overhead are in perfect sinc and the right chop is on the water. The rest of the time, it's too unstable and not talking chine walk, it does crazy stuff. I guess that's what happen's when you start pushing a boat built to run 60 max and push it 80.

One other thing, it's going to stress crack the deck around the back big time and if you're steering cables don't come straight out the back, they will probably need to, and need to be longer.

As for hook, mine had a shook in the pad, Stratos says it was suppose to. A friend to the hook out of his Javelin and lost 2 mph. If your's has one and you decide to take it out, I would wait until I had some time on the hull so you know what it will run and then fill it in with body filler so you can remove it and restore the hook if it has and adverse affect.

The boat is a1994 model.I can get it for $2800.00 less engine and its pre rigged for OMC.You cant even hardly buy a boat anymore without an engine unless its an allison or bullet,etc...I already have a 6 inch setback jackplate that I would use since I already have it.I figure for that price It can get me back in the water until I find something better and then I can resell it.If I do get it Im just going to bolt it together,Im not going to take the hook out.It should be scary enough like it is.My kind of fun.
