Pulling Propellers - PHOTO 2
What are the specifics of using a PropSmith? To keep the propeller shaft from turning while you remove the shaft nuts, place a 2-foot long scrap of wood (a 4-inch by 10-inch timber works nicely on many applications) against the hull and rotate the propeller tip against the wood. With the shaft nuts removed, thread the first PropSmith plate onto the shaft, stopping about half an inch before reaching the propeller hub. Slide the second plate in place. Then slide the long “puller bolts” through both plates and thread them into the propeller hub. Tighten the shorter “jacking bolts” by always following a five-pointed star pattern, crossing the shaft when moving from one bolt to the next. As the plates separate, the prop is pressured.
