So i saw that there are plans for an OB stand... but not an OB lift on this forum so I thought I'd post mine up. If people seem to like it, I can draft up plans and post a more comprehensive diagram of the unit. It's made of 2x4's ($16) one 2x6 ($4) and some chain and a come along winch (20 bucks at home depot)
You can also use for lifting the deck/cap off your boat!
I have an OB stand in one of the pictures, but I didn't use that. I used the dolly in the other pic so I could wheel it around and I made the dolly in less than 5 mins... It's some scrap wood and 4 castors!
