ABSTRACT:
An improved fin structure for attachment to the propeller shaft mount of a surface piercing marine outdrive apparatus. The fin structure has one fin member at one side of the mount for the propeller drive shaft of the marine outdrive. The fin member is so situated that it is in a position to destroy any side thrust exerted by the propeller on the water so as to avoid "walking" of the mount on the water and the propeller laterally.
