I used the Freeze-Off on a seized transom clamp screw on my ’56 30hp Johnson. Heated the transom bracket up with the torch real good then sprayed the clamp screw with the Freeze-off. The quick temperature change shrunk the clamp screw and it backed right out. Thought it might work on your flywheel but sounds like yours might need dynamite!
