Re: Help needed finding lift bolt for 90HP Force - Looks like the one Linked
The bolt hole sizes are 1/4 X 20. I use three bolts through a plate with a single eye bolt in the center of the plate. I fabricated my own because I do a lot of lifting. You can also use a steering wheel puller with the three bolts in the arms and an eye bolt in the center hole.
If you still want to find a screw on, of if you want to make one, the crankshaft nose is 3/4 diameter threaded something like 18 threads per inch. If you can find the correct nut and weld a loop to it, it will serve very well as a lifting ring.
