ABSTRACT:
An improvement in a lubrication adaptor for a marine steering system in which the lubrication adaptor is threaded onto a control cable housing and provides for the lubricated telescopic movement of a tubular member relative to the control cable housing, the lubrication adaptor having a chamber extending between a seal and a clearance between the tubular member and the control cable housing for containing lubricant, the improvement including a tapered, frusto-conical surface contour configuration along the inner surface of the chamber, the frusto-conical configuration being oriented with a smaller diameter adjacent the seal and a larger diameter adjacent the clearance for urging the lubricant in the direction away from the seal and into the clearance.
