  • 970cc Sea Doo engine

    I have a 970cc engine that was built from a 787. It was built by me in 1997 and has competed in many racing events, winning quite a few of them along the way. I bought it back from the guy I built it for. It came back disassembled, but complete, including the hardware. This engine sold for $5500.00 when new.
    The parts I got were,
    1 OEM 4mm stroker Sea Doo racing crankshaft in good usuable condition.
    1 OEM counterbalancer.
    1 set of 787 cases, machined for the stroker crank and fully race ported by Mel Miller. Has RV shaft and gear installed in it.
    2 big bore oem clyinders fully race ported to 1000R specs by Mel Miller, including two rave valves with housings.
    2 used Honda pistons with wrist pins and bearings.
    1 Miller billet racing twin plug 1000R 54cc head.

    This engine just needs to be honed and put back together. It is a perfect engine for a 1995-1999 XP, SPX or GSX hull. It will make an x-4 hull go over 70 mph with the proper related parts. Unbelievable accelleration.

    I want $1500.00 for it disassembled, or $2000.00 assembled.

    ( the clyinders alone are worth that much)

    Serious buyers only call weekdays 626 914 9509, ask for Bill.

    Wouldn't a 82mm stroke and 89mm bore yeild a 1020cc motor? CR500 pistons right? Killer price either way.

      Steve,
      Yes, a 82mm stroke and a 89mm bore equals 1020 cc, but a 787 comes with a 74mm crankshaft and if you add 4mm to the stroke it is 78mm. So, a 78mm stroke and an 89mm bore equals 970 cc's.
