90 hp sport jet flywheel help?

[stlsean]

I had a magnet come off of my flywheel. It still runs great at lower RPM's (when idling)but isn't running right at upper RPM's. I got a harmonic balancer puller today and the bolt holes line up but none of the threads are correct on the bolts that came with it.

Does anyone know the size / pitch of the bolts that are needed? (the three on the top of the flywheel)

Any hints on getting the flywheel off?

Also, does anyone know the difference between the Mercury manual for 1994 vs. 1995? I have the 1995 Mercury manual but not the 1994, and of course I have a 94 sport jet.

Any help is appreciated. Thanks.

Merc puller set comes with both 1/4-20 x 2-1/2 and M8 x 50 screws, so it should be one of those two sizes.

The 1994 and 1995 90 Sportjet use the same parts list, so there shouldn't be too many variations between them.
