I had built the actually geeignette for a boat, motor mount to the aquifer holder of a 5.30-meter Bayliner, In addition, I needed another 6 screws with nuts to the bracket to attach non-free. Nine hp auxiliary engine off and then release. I went on the Rhine from Dusseldorf to the marina Krefeld, without any problems in this Konstelation. It was really super. Thumbs up for this small and cheap Motorhalter!
