I just purchased a 94 waverunner III GP 701.. I think, I got 2 engines from the guy, he knew nothing about which is which and I assume I'm using the 700cc, heres a youtube vid of the engine running, anyone got any ideas which engine this is, I tried the numbers on the plate but couldn't find anything on the net. Tag says J500A 6K8

The volume in this video is pretty loud, might wanna turn your sound down.

I just figured out this engine doesn't fit in the hull of my 94 waverunner III.. :| anyone have an idea which machine uses a J500A? Thanks.
