I called ten tow truck companies and none of them would help. I bought a chain hoist from harbor freight for like $60 and it worked brilliantly.

I used the same chain hoist hanging from the bucket of the excavator, that way the lift was under control. Once out of the boat, I was able to move the motors and set them down where ever I wanted.

You don't have or know of anyone with an oak tree. Or any hard wood tree at that. Works fine.... At one point in my life I was shopless and garage door was not tall enough to back boat in garage. Otherwise if you have a garage you can always get a 12' 4x6 and catch as many trusses as you can. Depending on the span and center to center on the trusses not a bad idea to run a vertical 4x4 from floor to truss for extra support. Once set up 1/2 hour tops to pull it. Check with some friends or relatives. Just need to make sure the height is good.

To directly answer the OPs question it cost me $800 to have a tech yank the engine and drop in a new one. I had done as much of the derigging as I could.

I need to go on the road and start a new business. When I bought my 12 meter I had both engine out and on the shop floor in exactly 3 hours by myself. ssm drives didn't need pulling. Reinstall will likely take another 1 1/2 hours. Don't like to rush reinstall and double check everything. Over the years I've R&R a bunch.

I can completely understand the cost at certified merc shop as there's a lot of overhead etc. That list is long.

Where you at in Michigan?
