Years back I needed to remove an old V4 OMC and used my garage rafters. Garage was a trussed roof, so I added a 4x4 support from floor to truss about 8 ft apart and threw a chain fall around the lower truss beam. Had my neighbor come over, he is a big boy, 6'5" weighs about 340 lbs. He grabbed the chain fall and bounced up and down a few times, solid as a rock !! Used chain fall to lift off the motor and pulled boat out from under. Dropped motor in back of a pickup for the new owner. Kicked the 4x4 supports out and put them in the corner in case I ever need them again.
