This is the only flywheel I remember that would not eventually come off with normal means.
It was on a 40 hp Gale. I broke the OMC puller bolts, etc., from having the puller so tight.
Used a torch, whacked with a hammer, PB Blaster, etc.
I finally ended up destroying the flywheel to get it off.
Turns out that the flywheel key was terribly buggered up but the last guy
used it anyway.
Prepare to be boarded!
