Hiya George....

Here's what they say where I bought mine....

Flywheel Puller with lifting eye and crank shaft protector for Mercury, Mariner, Force, Honda and some Yamahas outboard motors with 1 1/2"-16 threads. It is made professionally in the USA on state of the art CNC equipment with 100 % quality inspection.

This model has heavy duty, 5/8 - 18 precision Grade 8 fine threads on the pusher bolt and the lifting ring. A higher quality unit than the competition.
