Lubricating an outboard motor's throttle cable appears to be a straightforward proposition: you add lubricant to the cable. What that description doesn't address is the adventure you face as you gain access to the throttle cable ends to which you must apply the lubricant. With a few twists of a screwdriver and a few taps of a hammer, you get a lubricated throttle control cable and the grand tour of your outboard's throttle control system.

White marine grease
Loosen the two remote unit mounting screws on the face of the remote control with a screwdriver. Pull the remote and cable away from the side of the control station. Place the remote face down on a flat surface and slide two books of similar size under the remote so that one is on each side of the control handle.
Loosen the control handle screw, recessed in the center of the back of the remote housing, three turns with an Allen wrench. Set a punch on the Allen screw and tap the punch lightly with a plastic mallet. Finish loosening the screw to remove the control handle.
Remove the screws on the back of the housing with a screwdriver. Pull the remote housing away from its cover. Apply a light coat of white marine grease to the throttle cable where the cable end enters the cable's flexible metal casing.
