Abstract

A truncated cone-shaped hollow body is provided and defined by a plurality of graduated size and axially spaced circular band portions interconnecting with a plurality of elongated circumferentially spaced slant height extending band portions with generally trapezoidal shaped openings or passages being defined between pairs of adjacent interconnecting circular and slant height band portions. The small diameter end of the body includes a generally radially inwardly projecting circumferentially extending annular portion and a cylindrical extension formed integrally with an extending outwardly of the inner marginal portion of the annular portion. The body includes a longitudinal slot extending the full length of the extension, through the annular portion and the two circular band portions adjacent the annular portion are interrupted between a pair of adjacent slant height band portions between which a radial plane of the body containing the said slot extends. The slant height angle of the slant height band portions relative to the center axis of the body lies between 35° and 60° (preferably approximately 45°) and a clamp structure is provided for clamping the slotted cylindrical extension about the generally cylindrical housing of a trolling motor, the slotted portions of the extension, annular portion and the interrupted portions of the circular band portions adjacent the annular portion defining a passageway through which to receive the depending blade-like skeg of an associated outboard trolling motor.
