Im in the process of tearing down my 96 750 Polaris watercraft motor. Spun a #3 rod bearing & broke the rod cracking the top half of the case & ruining the jug & head. A guy I found has a good set of cases & 3 bad cranks (same problem) off a 94 650 & 750. Would they be the same?? I think a full set of bearings & a new rod with the good cases would complete the bottom end at least. Do these cranks split in half with a pin or are they solid end to end? Any info would be helpful guys, Thanks.
