An elongated bar for lengthwise insertion longitudinally between the inner and outer sleeve portions of a marine propeller. The bar includes hook structure on the end to be inserted between the sleeve portions for hooked engagement with one of the generally radial lugs supporting the outer sleeve portion from the inner sleeve portion and a slide member is mounted on the other end portion of the rod and includes a laterally offset portion defining a recess opening toward the hooked end of the rod. The slide member is slideable along the rod into position to overlie and telescopingly receive an associated propeller retaining nut in the recess defined by the offset portion and a lock assembly is provided for releasably locking the slide member in position against movement away from the hooked end of the rod whereby access to the propeller retaining nut by a wrench or other nut removing tool is prevented and unauthorized removal of the propeller from the associated propeller shaft is prevented. As a safety measure, the propeller lock is free of portions which would interfere with normal turning of the associated propeller and thus inadvertent operation of the associated motor without first removing the propeller lock will not cause damage to the propeller or other associated running gear even though a turning propeller having the propeller lock mounted thereon will cause an apparent vibration so as to immediately remind a person who has inadvertently started the associated motor that the propeller lock has not been removed.
