Hello Joel.....thank you for your reply. I did take your suggestion regarding the 2x4 on top of the boom. Thank you! From there I looked at the situation a bit further and decided not to use a halyard to support the boom but build a simple A-frame under the boom. To me....this looks a tad bit stronger... worked like a charm.

Well, looks like, so far, I'm the only one removing my engine, lucky me! Smile. Having said that, I'll add a vew images and explain what I did, Maybe someone else can use some of my thoughts.

Block set up with 3x6 over the companionway. I watched as I loaded this idea. I thought I may have to support (off the cabin sole) say a couple vertical 2x4 to support the cabin top....didn't need it. Area is strong! I also used primary sheet winch to hand off from sink hand block.

Using sink hole, (hand block & tackle) and trucker hitch off mast base, I was able to haul engine out of bay.
