Abstract: The present invention is directed to an aerobic exercise device for exercising, conditioning, and toning body muscles. The aerobic device is formed of elongated tube sections joined together by a cylindrical, centrally located tension spring mechanism. A movable rod is contained within the tube sections and selectively displaced past a detent mechanism into or out of the cylindrical spring mechanism so as to respectively render the spring mechanism inoperable or operable. With the spring mechanism inoperable, the elongated tube sections and the spring mechanism form a rigid bar for exercising. On the other hand, when the spring mechanism is operable the tube sections can be forcibly pivoted about a central pivot point provided by the spring mechanism for muscle exercising. The preferred device is of sufficient length as permits the selective extension of the user's arms to their fully extended positions laterally from the body.

Abstract: A trolling motor for a boat including collar sections mounting the motor to the boat, a shaft leading from the mounting collar sections to the foot, a foot adapted to be disposed beneath the surface of a body of water, such shaft being hinged along its length such that the foot may swing from its position for propelling the boat toward a horizontal position substantially out of the water when the boat is powered other than by the trolling motor. The foot includes an alignment skeg and deflection shield mounted on the nose of the foot and adapted to urge the foot toward a horizontal position when the boat is moving forwardly under power other than the trolling motor.
