Does a 717/720 have 2 different connecting rods?

As I’m poking around online I’m noticing that you can purchase a PTO rod and a MAG rod with different parts #’s. Is that right? Seadoo had 2 different rods? Why would they do that and what is the difference? Can anyone shed some light on this?
Thx Chad

If you are looking at WSM then buy as they list it or better yet just get the kit.
Also keep in mind that rebuilding a crank isn't really a DIY job.

I get that. I was just curious. I know some motors use a different main jet size, but I’m guessing that’s because of the cooling flow?
