Locks the outboard motor in the forward position while trailering, greatly reducing the damaging effects of road shock. Does not "tie" engine's lower-unit to trailer, eliminating excessive pressure on hydraulic seals and unsightly scuff marks. Small compact mount can be easily stored in just about any boat compartment. Constructed of black powder-coated steel with stainless steel pins. Fits OMC, Bombardier '89 to present, 100 hp and up
