Abstract: The trolling motor for an overboard person comprises a trolling motor and a wrist worn device. The trolling motor may be a battery-operated propulsion device that is operable to propel and steer a water craft. The wrist worn device may be worn by a person on the water craft. A control unit within the trolling motor may communicate wirelessly with the wrist worn device and may be cognizant of a relative position of the wrist worn device with respect to the water craft. If the person falls overboard, a separation distance between the wrist worn device and the control unit may increase. Upon a determination that the separation distance has exceeded a predetermined distance threshold, the control unit may direct the trolling motor to energize, deenergize, or reverse direction such that the trolling motor may move the water craft closer to the person.

Abstract: An attachment for use with a safety chain which has a leading link and a following link, the attachment having a clevis with first and second lateral side sections and an opening between the side sections into which a leading end of the leading link is receivable; and a pin receivable by the first and second side sections so as to extend across the opening to couple the leading link to the clevis and a portion of the clevis defined between the first and second sections has a configuration complementary to a configuration of the leading end of the leading link; and/or portions of the first and second side sections have configurations complementary to configurations of portions of a leading end of the following link, such that there is a close fit between the clevis and chain when the leading link is coupled to the clevis by the pin.

Abstract: A fence clip assembly for securing strands of fencing wire and the like to wood and metal fence posts and including a pair of ears with holes therethrough and a main body with a wire holder that may comprise a pin to lock strands of wire to a clip by insertion through aligned holes in flanges and that is removable to allow the wire to be readily released and that further includes an insulator connector to insulate supported electrical wires at the fence poles.

Abstract: An engine fuel heater for internal combustion engines that mounts between the fuel filter mount and the fuel filter. Liquid fuel is directed through passages in the heater that are complementary to intake and discharge passages through the filter and filter mount. A heat exchanger is situated in or adjacent the fuel passage and operates to heat fuel entering the filter. Water from the engine cooling system, electrical elements, or a combination of both can be used as a source of heat for the heat exchanging elements.
