    Welcome to the Forum Mjet


    I would personally stay with an OEM NEW Yamaha crank.
    Yamaha uses better quality KOYO and SKF bearings.

    SBT has a good warranty on their motors, but as for their 66V cranks, I have heard of stories in the past of failures from the JBS or different brand bearings were used.

    I am not sure how the quality of those cranks are now, but I think most of the reputable tuners/builders would say to stay with OEM..

    I'm sure it would be fine on a stock motor.

    But, if you plan to do any mods, and/or it has sooem hours on it, it needs to be rebuilt, trued and/or welded by a reputable company such as RAD or Crankworks.

    I am not knocking the company SBT, they are great , I am just giving my opinion that I would personally stay with an OEM crank that deals with the 66V motor.

    My wife's 1998 Sea-Doo GTI has an SBT motor. Can't beat their warranty

    i went through 3 66v sbt motors in a 10 month period, granted they were all warrantied. all pv failures. the only reason the last motor didn't fail was that i did the pv's myself.

    I have a dumb question? If you have your crank trued and welded how do you get your bearings on and off. The breakdown on the crank assembly makes this appear as if it is put together using assembled parts, not like a car crank.
