Abstract: An electric motor for trolling at slow speeds and the like and comprising an elongated and generally cylindrical submersed unit which houses an electric motor that in turn drives a planetary gear system that in turn drives the propeller. The planetary gear system includes a compact gear assembly which can be assembled ahead of time and quickly inserted in the gear housing. The internal gear ring of the planetary gear system is quickly and easily secured within and to the gear housing only and by means of cap bolts extending through the gear housing and into engagement with the ring gear, the ring gear being preassembled in the gear housing. The motor also includes a bearing support in which are preassembled anti-friction bearing assemblies. A rear sleeve thrust bearing and a front sleeve thrust bearing are located on opposite sides of the gear assembly and act to threadably support the gear assembly and absorb axial thrust.

Abstract: An outboard motor provided with a horizontally elongated marine propeller drive housing having a shaft journalled therein and a marine propeller mounted on the rear end of the shaft. A weed guard is mounted on said rear end of the housing and surrounds and encloses the propeller, the weed guard has a tubular section at its front end and attached to the housing, and the guard also includes a rearwardly and radially outwardly diverging tapered wall having a series of radially extending spokes which are relatively thin in circumferential direction as compared to their axial width. The guide also includes a cylindrical portion integrally connected with said tapered wall and disposed radially outwardly from and surrounding the propeller and extending rearwardly past the propeller. The cylindrical portion is perforated so as to be substantially open to permit the passage of water readily therethrough.

Abstract: A compact, light weight and easily detachable power unit for driving a golf bag cart by means of an electric motor carried by the unit. The unit includes an articulated frame having an attaching portion which is quickly attachable to or detachable from the frame of the golf bag cart and this attaching frame also carries the battery. The articulated frame also includes a motor and wheel driving frame which is pivotally mounted to the attaching frame about a generally vertical axis and extends generally downwardly and rearwardly therefrom and has a ground wheel at the lower end thereof for castering relative to the attaching frame. An electrical control circuit includes an electric motor carried by the wheel driving frame and also includes the battery, a transistor, a resistor, and a manually operated variable resistor controller on the golf bag cart to infinitely vary the driving speed of the motor.
