Outboard bracket

[KINGFISHER 9]

Anyone fitted an outboard bracket to the back edge of a swim platform so that they can fit an outboard as an emergency spare? ... extra long shaft 9+hp probably liftable in a crisis and would give a certain amount of speed once you got it moving! I once towed a 5 ton saily boat with a hard dinghy tied alongside powered by a 2hp Yamaha ... went very well on a calm day! Just pondering at the moment but presumably it would be an L shaped bracket bolted through.

Very common way of mounting a standby auxiliary. You need to make it strong enough to take the considerable thrust which will almost certainly mean bracing struts forward. Make sure you get the height correct for the shaft of your motor. If your bathing platform is just above the waterline you will probably find a short shaft is right - top of mounting board 15" above static waterline.

Yes, the shaft measurement goes from the outboard bracket, therefore the top of the mounting bracket fixed to the boat ... to the bottom of the cavitation plate .. no idea of the distance from the platform to the water ... currently away from home ... short shaft wouldn't get enough in the water would it?

Yes it would if you set the mounting board at the correct height. First measure the distance from the top of the platform to the waterline, subtract that from 15" and see if that is enough to get a board onand take the clamps of the motor. If not then a long shaft will need the board 20" total above the waterline.

One advantage of a short shaft is that it can be used on a small RIB or inflatable sport boat.
