I agree with rsn48 regarding Seawise davits. I had Weavers but over time my wife and I realized that one or both of us was going to get wet or hurt hauling the dinghy up and down and then lifting the outboard
in and out of the floating dinghy. We went with Seawise. They are expensive but well engineered and built.
I worked with a local machine shop to modify a 35mm hole saw so it fits over the handle crank and used an 18v drill to power
the dinghy up and down. EZ.
