Just figured I'd share how I got my stuck flywheel off. I had purchased a flywheel puller from an auto parts store, I soon learned why the OMC puller is round and a 1/2" thick, the puller started to bend. I got a 5lb weight and made a rubbing of the top of the flywheel so I could match the puller holes and drilled the weight so I could put it on top of the puller(this gave the rigidity to prevent bending), using grade 8 bolts (from tractor supply company, the cheapest place to buy hardware as they sell by the lb at a very good price) I installed the puller setup on the motor and started tightening, I used a 4 foot crowbar trapped between the grade 8 bolt and the crank and a 1/2" breaker bar with a 4 foot piece of pipe to gain leverage. I tightened the puller bolt an 1/8 of a turn at a time, repositioning the breaker bar for best leverage, when it finally came off, it sounded like a gunshot and the puller jumped about 4 inches up off the motor with the flywheel attached. It wasnt easy and I tried numerous things, including heating the flywheel. Upon removal I understood why heat didnt work, the center hub of the flywheel extends down quite a bit so therefore you couldnt get enough heat into it to make it loosen up, I did get a new flywheel and tried cutting the flywheel off, but upon getting the outer part cut off I noticed there was no way to cut that extended center section without destroying the stator and sensor which was another $350 in parts. I had nothing else to loose by trying to pull it again and using the 5lb weight, crowbar and pipe I gained enough leverage to get the flywheel off. I hope this helps someone else to understand the extreme you may have to go to get it done.
