I posted this recently on a generator install in a different boat type. It might give you some ideas on a gantry.I think I could actually leave that engine on and just keep it in neutral at idle to flow water through the dripless if I had to. Everything is neutral at this point, and the shaft spins in forward and reverse as well. My mechanic is 8 or 9 miles away, but he's offered to come over and replace it in my slip with me. I think it's around 109 pounds. Wonder if I need to rig up some sort of sturdy A frame/sawhorse to lower it down into the lazerette with a come a long or chain hoist? Or can you manhandle one in and out? Has anyone done it?
