That makes more sense to have the puller holes in a steel hub!
One stripped aluminum bolt hole is enough. I was kind of surprised
that my heli-coil held up. When I first heard that big "bang" when
the flywheel released, I just hoped it wasn’t something catastrophic!

OMC made a change in their Big Twin flywheels around 1958-ish. The revised hub has a flange that the puller screws into. The one in the picture is the old style where the flywheel could be pulled off of the hub. Worse, they often broke loose.

Prepare to be boarded!
