发明名称 Engine propeller blade and lower unit protector
摘要 The propeller and lower unit protector is made from a high grade steel and has a spring like U-shaped top member for sliding in a generally horizontal direction over an outboard engine cavitation plate from a front to a back portion of the engine. A generally ring shaped member depends downwardly from a first end of the top member and is attached thereto. The ring member is spaced apart outwardly from the outer edges of the propeller blades. The opening in the front of the U-shaped top member is closed by a bolt through a bore in the first end of the top member to secure the top member in a tight grip around the lower engine housing. The closed end of the top member is attached to a strut depending downwardly and backwardly to attach to a bottom portion of the ring member. Port and starboard side struts also connect the downwardly depending strut to a middle portion of the ring member.
