Bruce, you may have posted this question before you were a premium member and no longer need an answer but your torque specs are on page 13-02-5 of the Seadoo shop manual for 1999.
When doing a torque on most anything, you start in the middle and criss cross in an "X" pattern, working outward. But that procedure is also in the manual.
I know you've shot me PM on this before, feel free to PM me if you need more help.
