One of the fingers includes a distal end and claw in spaced relationship thereto which cooperate to provide a fulcrum for movement of the lever, thereby to facilitate the removal and replacement of nuts which are locked on a threaded shaft by a locking member having bendable tabs projecting outwardly therefrom. ## Claims ### Claim 1 A combination tool for use in removing and replacing a nut which is locked on a threaded shaft by a locking member having bendable locking tabs projecting outwardly therefrom, the tool comprising an elongated lever having a proximal end section including a handle, a distal end section including a first finger for engaging and bending one tab upward upon movement of the lever, and a second finger for engaging and bending an opposing tab downward, the two fingers being separated by an outwardly opening space, and a wrench section interposed between the two end sections for engaging the nut, the first finger including means for engaging both upper and lower surfaces of the one tab, thereby to provide a fulcrum for the movement of the lever to bend the one tab upward and the opposing tab downward. ### Claim 2 (depends on 1) The tool as recited in claim 1 wherein the second finger extends slightly further outwardly than the first finger for engaging an upper surface of the opposing tab, thereby to bend the opposing tab downward upon movement of the lever. ### Claim 3 (depends on 1) The tool as recited in claim 1 wherein the end sections are provided in the same plane and the wrench section is offset from the plane of the end sections and integrally joined thereto by web portions. ### Claim 4 (depends on 3) The tool as recited in claim 3 wherein the wrench section includes an aperture which is adapted for engagement with the nut and a downwardly projecting alignment detent for engaging the locking member, thereby to align and simultaneously move the nut and locking member upon rotational movement of the lever to tighten the nut on the shaft. ### Claim 5 A combination tool for use in removing and replacing propellers which are mounted on a propeller drive shaft by a nut and a locking member having bendable locking tabs projecting therefrom, the tool comprising an elongated lever having a proximal end section including a handle, a distal end section including first and second divergent fingers, and a wrench section interposed between the end sections, the first finger including a distal end for engaging an upper surface of a selected tab and a claw in spaced relationship to the end of the first finger for engaging a lower surface of the selected tab, the engagement of the distal end of the first finger and the upper surface of the selected tab providing a fulcrum for movement of the lever, thereby to bend the first tab upward, the second finger extending slightly beyond the first finger for engaging an upper surface of the selected tab, engagement of the distal end of the first finger and an upper surface of a tab opposed to the selected tab providing a fulcrum for movement of the lever, thereby to bend the selected tab downward. ### Claim 6 A combination tool for removing and replacing a propeller mounted to the drive shaft of a boat engine by a nut and a locking member having bendable locking tabs projecting therefrom, comprising a generally Y-shaped lever having an elongated shank forming a handle and two distal fingers extending angularly therefrom, one of the fingers including a distal end at generally a right angle to the longitudinal axis of the shank and a claw in spaced relationship thereto for simultaneously engaging upper and lower surfaces of one tab, thereby to bend the one tab upward upon movement of the lever, and the other finger extending slightly beyond the one finger for engaging the upper surface of the one tab, thereby to bend the one tab downward upon movement of the lever, the distal end of the one finger engaging the upper surface of the one tab to provide a fulcrum for the movement of the lever to bend the one tab upward and engaging the upper surface of a tab opposed to the one tab to provide a fulcrum for movement of the lever to bend the one tab downward.
