Abstract: An ancillary tiller provides a first shorter arm releasably interconnectable by mounting structure at its first end to an outboard motor and movably interconnecting by articulating linkage at its second end a second longer elongate arm. The motor mounting structure is adapted for selective interconnection to a motor shaft, tiller or guide grip. The articulating linkage interconnecting the first and second arm is of a combined axle and ball and socket type that allows universal positioning of the second arm relative the first arm and provides locking mechanism to releasably maintain such positioning. The second arm comprises two slidably related elongate elements having locking mechanism communicating therebetween to releasably maintain a selected length. The ancillary tiller is particularly adapted for steerage of small fishing boats powered by steering outboard motors.
