Super Jet Motor alignment question on rn sj.

[snirunner24]

So the motor is shimmed correctly but the horizontal is off. The spacing in the coupler on the right side is just shy of 1/16 wider then the left. Is this something i should be worried about of should I leave it. The motor was just put in over the winter then I bought the ski so it was never run like this.

Try taking a shim out of the 2 front motor mounts.

If I was to work on it I would just slide it into place but I don't want to if I don't have to. I can't get to the bolt under the b-pipe so that will have to come out. If I have to no big deal.

just run it.

That's what I was thinking but I'm not sure how accurate it has to be I would rather take the time now then have a vie problem later. But with that being said the deference is slight.

I think it should be okay to run and see if you get a vibration. You would be surprised how little vibration you get from being quite a bit off. Probably a little extra wear on the midshaft housing though. Also try just moving the motor around a bit on the mounts until you get a better fit and tighten everything down.

I recently bought a ski (99sj with 760, b pipe, head, etc) and ran it for several months and it was fine. Then I replaced the midshaft housing and when we went to re shim it I ended up addling like 8-12 additional shims to get it lined up right (using a proper feel er guage). Does not feel any different even though it must have been WAY off before.
