ABSTRACT:
A marine spare propeller mounting device used for safely securing a marine spare propeller on board a recreational or work vessel powered by common sterndrive units or large outboard motors. This invention includes a plastic base plate (2) that accepts a stainless steel center axial shaft (3) as well as a stainless steel thrust washer (16) and a retaining knob (4). The stainless steel thrust washer (16) is slipped over the stainless steel center axial shaft (3) and the retaining knob (4) is started on the threaded end of the center axial shaft (18). Then this assembly comprised of the stainless steel center axial shaft (3) and the stainless steel thrust washer (16) and the retaining knob (4) is slid through the propeller hub housing (6) leaving the head of the center axial shaft (13) exposed enough from propeller hub housing (6) to allow the head of the center axial shaft (13) to be inserted into center axial shaft mounting slot entrance (10) while propeller exhaust flange (9) is held above base plate raised retaining ring (7). Then the assembly is slid into its final nesting position with the head of the center axial shaft (13) being against the square end of the center axial shaft mounting slot (15) and the propeller exhaust flange (9) is seated in the base plate raised retaining ring (7). Then the retaining knob (4) may be tightened against stainless steel thrust washer (16) and propeller hub housing (6) thus retaining marine propeller (1). This invention will hold the above stated spare marine propeller safely in its assigned storage location on board a marine vessel.
