ABSTRACT:
A combined support and lock device (10) has a longitudinally extending support portion (20) and a longitudinally extending lock portion (50). The support portion (20) includes a centrally disposed strut (22) having a first end (24) and a second end (26). The first strut end (24) is adapted to rest against a member (8) of a boat trailer frame (6). The second strut end (26) is adapted to rest against a portion of a boat motor (12). The lock portion (50) includes a hook-like rod (60) having a first end (62) and a second end (66). The first end (62) of the rod (60) is curved (64) so as to engage a recess (18) defined within the rearward portion of the boat motor propeller (16). The rod (60) extends between two adjacent propeller blades (17) to prevent rotation of the propeller (16). The second end (66) of the rod (60) is lockable within a pivotable locking flange (52) the locking flange (52) being rotatably secured to the second strut end (26) of the support portion (20) of the device (10).
