Joe, What I have on there is this aluminum block, which I got on a motor, at least 15 years ago. I searched for Ray in the members index at that time and he wasn’t listed. The plate on top of it is for my extended tiller. However on the OA-55 I’ve been working on there is part of an aftermarket device to attach a line should the motor jump off the back of the boat. It seems they are still in business. Bob I’ve sent you a PM .

A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
