Wedge Dimension and motor mount
The wedge for the O'Day 20 measures 5.5 inches wide by 9.5 inches long. The Garelick motor mount folks have been talking about (71090) is 8.5 inches wide. I wrote to Garelick and they said a new wedge would need to be built to accomodate the new bracket. They also sent me detailed specs on the mount, including measuring for installation.
