We had Weaver davits, but moved everything to Sea Wise. It is much easier for us. We have a 20 hp Tohatsu 4 stroke with electric start. It stays upright as the dingy is raised. We use the Sea Wise cable and crank to raise it. I believe it has 25:1 gearing. It is easy enough my wife can raise or lower the boat by herself.
The PO bought the dinghy and put the Weaver mounts on the boat. At the time the dinghy had an 8 hp motor, no seats, steering, etc. It is a big inflatable. It was awkward for us to get the boat up and down with both of us working on it. We found we were reluctant to use the dinghy because it was such a pain to tip up and down. That took the fun out of it for us. We moved to the Sea Wise davits, the 20 hp motor, seats, and steering all at the same time. The inflatable is heavier, but I can just about crank it up with one hand. If it is not easy, it won't get used. At least that's our experience.
