Outboard 'safety' brackets
OK, I know that's probably not the correct term.....
But on both my outboards there's a spring loaded bracket to support the engine when tilted up.
Previously I always tilted the motor up and supported it on this bracket for trailing, dropping the motor back down for flushing and storage when I got home.
The chap who sold me my new boat advised that he'd been told that the bracket was only for use when working on the engine, and trailing it with the bracket in place put strain on the other brackets/mountings etc?
