Anyone have any home fabricated rock guards for their outboards? Let's see em'. I need to fab one up for my '72 rude 6 hp fisherman and I need some ideas. I can't use a Mac's River Runner because you need to bolt through the skeg and the skeg on this motor is also part of the lower unit oil housing so drilling is a no no. My only option is to bolt through the cavitation plate. I fish the mighty Susquehanna here in PA and it's nothing but big rocks and rock ledges that like to eat up props.
