Re: 20hp mercury flywheel
Might want to try a small engine shop. All you really need is a 2-point puller with grade-8, 1/4-24 (fine thread) bolts. Most Briggs & Stratton type flywheels are 2-point pulls.
If you removed the flywheel from the hub, then I hope you marked it first, as the magnet placement is tied to the point gap. It it is not aligned correctly, things could get tricky...
