Adaptation of Zerotrees Using Signed Binary Digit Representations for 3 Dimensional Image Coding

A marine propulsion device comprising a propulsion unit adapted to be pivotally mounted on the transom of a boat for pivotal movement relative to the transom about a generally vertical steering axis, the propulsion unit including a rotatably mounted propeller, and a powerhead drivingly connected to the propeller, a steering handle connected to the propulsion unit and extending generally horizontally therefrom for causing pivotal steering movement of the propulsion unit in response to lateral movement of the steering handle, and an extension handle assembly removably attached to the steering handle and including an extension handle, a coupling device including a plurality of fingers spaced around the steering handle and having respective inner ends pivotally connected to the extension handle, and respective outer ends biased outwardly from the steering handle, and a cylindrical sleeve surrounding the coupling device and being slideable around the fingers longitudinally thereof for moving the outer ends inwardly such that the fingers grasp the steering handle.
