Re: lifting a 1978 115 HP inline 6
Jimg, I use a piece of steel plumbers strap that I bolt to the flywheel, using two of those 5/16 fine thread inner flywheel bolts. Bolting a harmonic balanacer puller to the flywheel (3 5/16 flywheel bolts) would be even better. I have a cheap block and tackle that I use for the lifting. The motor is only 300#.
You can use a cable hoist (Cumalong), from the HW store for $20.
