    I would suggest replacing that old Rockwell driveline with a modern Spicer 1310 or 1350 driveline and a flywheel button. Either size will handle the job. If you get the U-Joints without the zerk, they are stronger.

    X's 2 on the 1350 for your application heres a link and a couple images from us that may help Tom

    Jet Boat Performance, Drive Lines

    1310 Drive line, this is the most common modern replacement H-bar drive line for jet boats. The overall length measures 7 1/2", the round register on the flang measures 2 3/8" and the rectangular bolt pattern measures 2" x 2 3/8"



    Heavy Duty 1350 Drive Line, The overall length measures approximatley 8", the round register on the flang measures 2 3/4" and the rectangular bolt pattern measures 2 3/8" x 2 7/8".

    Turbo wog, this is what I use. Its the 1350 series spicer joints that arent crossdrilled . I exploded one with the smaller 1310 joints. It was a bad deal took out the drive line cover as well as the intake valves and a few other things. I had Drivetrain Specialties in OKC build this one and balance it. They recommended that i have it rebalanced any time I have the joints replaced. I have the joints replaced every yr. My engine is exactly in line with my pump. If this deal ever blows the next step up would have to be a Lenco shaft.

    how much hp were you running at the time & did it break right after launch or in the middle of a hot pass? was there a chance the joints were getting loose when it happened or was it all fresh? were they the solid or greasable u-joints at the time. do you have to regrease the 1350 within the year?

    They were the 1310 joints and werent crossdrilled and they were put in at the first of the yr. It was about mid summer. The grease should last for the yr. You have to disassemble to grease them so I just have new joints put in at that time.
    It was with my old draw through system and a 325 shot of nos. It was at the top end of the pass. I was running 115+ in my old youngblood TX20.

    Paulie, that 1350 from Tom looks badass, I'd move the motor if I had too, to use it!
