Electrically conductive plastic bushings for marine propulsion devices

Abstract From the Canadian patent

A marine propulsion device is provided including a propulsion unit adapted to be mounted on a boat for pivotal movement relative thereto about a generally vertical steering axis, the propulsion unit having a propeller shaft supporting a propeller an, internal combustion engine drivingly connected to the propeller, and a corrosion protection system which, device also includes at least one bushing made of a conductive plastic to allow a path for electrical connection to the corrosion protection system to be established across the bushing.
