RE: seamaster engine mount from plans?
My rudder is made of wood and is held in position by using a nylok(sp???) nut with enough tightness to hold in place. but loose enough to swing up if it should strike something in the water or beaching. Nice to have that swing away feature. Engine mount idea is interesting, but seems like alot of work, used nylon mount on mine, not much of a weight penalty and it is located near the CG.
