Yamaha Waverunner III (650cc 1992)

[PJDK9020]

I am rebuilding the jet unit on my 1992 650 Waverunner III.

Can anyone assist me in the re-assembly sequence of the jet unit? i.e., do I press the bearings onto the shaft and then press the shaft and bearing into the duct impeller or what order do I do this?

Thanks very much. Don't have the model/serial available at the moment (I am at work) but the sequence makes sense. I "press" the front bearing in then "press" the shaft onto that then "press" the back bearing in and then install the new impeller.

I'll let ya know how it turns out.
