I have an 85hp force 1988 and I have been trying to get the flywheel off for days now. I have soaked it in pb blaster ( supposed to be wd40 on steroids) I have a good puller and I have grade 8 bolts. I am tightening puller to so much force I have broken a grade 8 bolt and tapped the puller screw with a hammer and it still won't break free. I have even tried prying up a little on flywheel and or hitting it upward with a rubber mallet. I don't want to damage the flywheel and especially don't wanna damage crank bearings with so much pressure on the puller screw against crank but it just will not break free. Anyone have a little tricks or ideas because I've never met a flywheel this stubborn. I don't wanna use a torch to heat it cuz it may damage stator or something else. Any advice please!!!! I'm getting frustrated to a point where I want to smash the dang flywheel off and replace it and the stator if it breaks.
