Built to hold motors up to 15 hp or 100 lbs/45 kgThe Edson Stern Rail Outboard Motor Mount is built to hold motors up to 15 hp or 100 lbs/45 kg. Convenient cleat and side handles allow you to tie the motor and lock it safely on board. The non-corroding polished 316 stainless bracket with nonskid pad, bolted to the UV stable poly backing board always looks shipshape... no more varnishing. Comes complete with hardware to attach to any standard 1'' (2.5cm) stainless rail Bottom cleat comes unattached so that it will fit any rail spacingWarning: Be sure the engine is securely tied onto the backing board and the engine mounts are tightened whenever the engine is stored on Edson's Outboard Motor Mount. Use the tilt feature on the engine to allow the lower unit to rest on the backing plate or add a block of wood to provide this support.
