ABSTRACT:
Tools having utility in the repair of outboard units. A first tool pulls a propeller off its shaft, and a second tool pulls a bearing carrier off the shaft and removes it from the inside of the outboard unit. Both tools include an elongate screw that axially advances to affect the desired pulling and both tools engage radially disposed struts of the item to be pulled when operatively deployed. The housing of each tool includes puller members terminating in strut-engaging mating surfaces at the distal free end thereof that abuttingly engage the struts from behind and exert a pulling force against them as the screw is rotated.
