Screw size Flywheel Puller 1972 Johnson 125hp

[LOSTBOATER72]

Any Assistance?<br /><br />I am attempting to replace a piston in the motor listed in the subject of this posting. I am having a problem with pulling the flywheel with miscellaneous types of pullers. Does anyone know the screw size and threads to use on this flywheel so I can pull it and move on with my "chore"? Thanks in advance.<br /><br />LostBoater72 in Sacramento, CA<br />
