发明名称 Protective cover and method for protecting a boat propeller shaft
摘要 A protective cover and method for protecting a boat propeller shaft and gears within a lower gear housing of a boat includes a cone-shaped casing having an inner surface, an outer surface, a top, and an open bottom. The inner and outer surfaces have an edge in common in which two notches are formed and extend along the inner and outer surfaces. The notches are spaced 180° apart from each other and are aligned with and placed around the skeg and upper frame of the lower gear housing of the boat so that the propeller shaft and gears are covered. The casing is retained on the lower gear housing by an elastic band.
