    First....run it on the trailer,in the water,for a few minutes with the seat off and check for leaks.Make sure you are running a few ounzes of extra oil per 5 gallons.

    1 Take it out for about 15 minutes and dont go over 1/4 throttle and ALWAYS fluxuate throotle,NEVER leaving it at any given rpm.Come back and let it cool down for 15 minutes with seat off.

    2 Same thing,go from idle to 1/4 and then sneak in some 1/2 throttle bursts,again,never hold at one rpm.FLUXUATE! After 15/20 minutes,came back and let it cool down for 15/20 minutes.Pop the seat once in a while and check for leaks...

    3 Go from idle,to 1/4 throttle and do some 1/2 throttle bursts more often than last time.You can now do some 1/2-3/4 throttle bursts,dont hold it there more than 5 seconds.Do your cool down after 15/20minutes...

    4 OK......go out and put some hours on it,never holding it at any given rpm.You can do a few full throttle blasts now but dont get carried away.Make sure your ski is running on the rich side before you even run it.Its always a good idea to bring a fresh set of plugs with you incase you foul with the extra oil and rich settings.Take your time,this is very boring but i have had very good success with this procedure and have been doing it this way since 2001.

    BOTH ...it is for all engines......and as quoted on his site.>>>>
    and woody stated, its important to do the cooldown every 15 minutes.

    * and to reiterate, stay out of nowake zones and vary that throttle.




    Although the examples shown here are motorcycle engines,
    these principles apply to all 4 stroke engines:

    Street or Race Motorcycles, Cars, Snowmobiles, Airplanes & yes ...
    even Lawn Mowers !!( regardless of brand, cooling type, or number of cylinders. )

    These same break in techniques apply to both steel cylinders and Nikasil, as well as the ceramic
    composite cylinders that Yamaha uses in it's motorcycles and snowmobiles.

    Because you cant vary throttle from 1/4-full for 15-20 seconds in a No wake zone....unless you want to get busted....or your ski is THAT slow....lol...
