Abstract
A boat propeller lock for boat propellers of the type that include a central shaft with a plurality of outward extending propeller blades, and that attach to the drive shaft of an outboard or inboard/outboard marine motor is provided. In one embodiment, the invention includes a generally U-shaped member consisting of a base member and a pair of parallel arms. A generally C-shaped member having a pair of parallel arms extending perpendicular to the C-shaped member, with one arm extending from each end of the 'C' of the C-shaped member. The U-shaped member being adapted so the base member fits the front portion of an outboard or inboard/outboard lower unit with the parallel arms facing aft of the lower unit, and the C-shaped member being positioned over the rear of the marine propeller with the parallel arms facing forward. The parallel arms of the U-shaped member being slidably engagable with the parallel arms of the C-shaped member. One of the members includes a locking portion that permits slidable engagement of the parallel arms, but prevents disengagement thereof unless the locking portion is unlocked. At least one of the parallel arms can include a plurality of longitudinally spaced ratchet teeth. The lock portion can include a pawl adapted to engage the rachet teeth to permit the U- and C-shaped members to be slid together while preventing the members from being pulled apart when in the locked position.
