Power steering adapter for outboard powerheads of various size

An adapter for the coupling of a power steering servo unit to a mounting bracket of an outboard motor powerhead to steer a boat;

• the outboard motor powerhead being carried by a mounting bracket pivoted on a horizontal transverse mounting axis to a clamp frame secured to the boat and having a turning center axis from which a steering bracket extends forwardly, the steering bracket and powerhead turning center axis being adapted to swing with the mounting bracket about said transverse axis,
• the power steering servo unit having a reversible motor fixed to the steering bracket and with a drive pinion on a drive axis and a segment gear meshed therewith to shift the servo unit transversely about a steering center axis parallel to and eccentrically spaced from said turning center axis of the mounting bracket, there being a tiller member extending rearwardly from the segment gear and in radial alignment with said steering center axis,
• the adapter for coupling of the servo unit being comprised of a mounting tube rotatable on the horizontal transverse mounting axis, and a forwardly open anchor member carried by the mounting tube and having an anchor socket slidably receiving the rearwardly extending tiller member and pivotally engaged with said tiller member for lateral angular displacement of the tiller member within the anchor socket,
• whereby lateral displacement of the steering center axis from the turning center axis is accommodated for when the powerhead is turned.
