    Default fastest outboard

    as far as stock outboards go...is the merc 300xs the highest performance model? Anyone else make a more powerful (given weight) model?

    Are 2 stroke OB's banned on major lakes?

    they make a 2.5 drag which from my understanding makes around 330hp but also tacs much higher RPM then the 300xs but doesnt have the torque the 300 does so you wont be able to run a larger prop

    this is just my understanding so dont take it to heart

    The 300 xs turns 6400 rpm and you can get a 1.62 gear ratio but is heavy at 505 pounds and the shortest gearcase is 20 inches. the 300 drag turns over 9000 rpm is around 350 pounds and a 15 inch shaft. Both engines are great. The best thing about the XS motor is a warantee PS the fuel milage of the XS motor 50% better

    Non emmission rated 2strokes are banned on a few lakes but those that are rated are fine. Tahoe is the toughest right now and requires 2 star rated engines, the others are 1 star.

    1 star started in 2001 in Ca
    2 star in 2004
    3 star in 2008

    oh yah forgot but steve reminded me that the 2.5 drag is available new but its high priced no warranty at all

    the 300 i believe isnt as much price wise and comes with a warrantee

    If $$ isn't an object and you're just trying to get the biggest HP outboard, get a hold of Eric Simon. He has a 3.4L Stroker that is cranking out 385HP with an available custom lower in which it runs a 15" shaft. Bad@$$ engine for sure. But I think its going to set you back around $35K. He has them brand new, and also offers a 1-year warranty on them if my memory is correct. Ridiculous cool!
    Not fresh out of the Mercury crate, but 100% worth looking into.

    Just my $0.02

    A friend of mine said Merc has a 5.7 coming out soon. He is a outboard Merc trained guy. He just went to school on it. He said something like 5-600 HP with slight work over. I don't think he lied to me. But if you can't lie to a friend who can you lie too.

    Yes, and how about the Evinrude 7.4 2 cycle diesel thats coming out? This is a hybrid 2 stroke that you can use diesel and castor bean oil along with R50 or a special blend of Sunoco and a water based oil that was developed back in the 1920s most commonly used for french frys but now being introduced to the high performance outboard world.

    I think the more important issues is, what boat are you going to put this motor on and what it isn't intended use (hot rodding, dragging, performance lake boat, ski tower, etc). There are benefits and drawbacks to everything. What's your budget too?

    I agree with Keith it really depends on what you want out of the motor! In my opinion though the drag motor is far superior in all out speed than the new green motors. The drag motor can give you the best of both worlds you can put a small prop and twist the thing to the moon for drag racing or throw a big prop on and put up alot bigger numbers than any of the green motors! Also you can probably rebuild 3 drag motors to the price if one 300xs!
