Early type Evinrude Simplex two lever throttle/shifter. This unit had been service every couple of years according to the service manual. It was disassembled, cleaned greased and the cable ends removed so lube oil could be inserted in the cable housing. To work the lube oil into the cable sheath I removed the cable end and put the end of the control wire into an electric drill and turned the wire while spraying lube oil into the sheath. It is amazing how much this improved the movement of the control wire.
