摘要 |
A propeller nut designed to replace a conventional hexagonal nut to secure a boat propeller to a motor. The propeller nut includes a leading portion and a trailing portion. The leading portion has a nut part having internal threads sized and configured to engage external threads of a drive shaft and to secure the boat propeller about the drive shaft and a diverging part extending outwardly from the nut part to a maximum outer circumference. The trailing portion extends from the maximum outer circumference to a trailing end of the propeller nut, wherein the trailing portion has an outer surface that converges from the maximum outer circumference to the trailing end. |
