Outboard Flywheel Is Not Coming Off

So I have a 1989 Sears Gamefisher that has the original Sears 15hp outboard motor. I am having issues replacing the coils because there is no way to get the flywheel off. There are no threaded holes on top to use a Harmonic Balancer/puller. I have tried doing almost all of the video methods posted around and have oiled the center pin, and have tried the hammer and prying method on both sides. If anybody has any helpful info on this, I would greatly appreciate it! I will attach pictures as well for some more info/understanding. I could not find much as i was looking around for this specific issue. Thanks all!
