I know that engines are often hoisted out using a block and tackle attached to the boom. I'm sure that is a fine way to go about it, especially with a small engine. However the marina where I'm at happens to have tall mooring posts that served my need for an attachment point to support a lifting hoist. I didn't want to bolt anything to the post so I opted to use line instead and tie the "mast" portion of the hoist to the post. Wrapping the line to the post in a figure eight enabled the line to serve as an upper hinge with over 90 degrees of rotation. The bottom of the post pivots on a pin made from a plumbing flange and a short length of 3/8" pipe. Here's a picture of the rope hinge. Can you tell I'm having fun with this.
