    Default 1954 Rivera Hercules engine

    The past three years, the pin on the shaft from the engine to the prop breaks when the boat is engaged in reverse from neutral usually while docking. Speed cannot be an issue since the boat is not even travelling 1 knot. Any thoughts?

    Pin or Key?

    I'd guess the hole (keyway) is worn and until made 'snug', they will keep snapping...
