About this part

Shift cable bellows referenced to Mercury Marine and Quicksilver 74639Q02 and 74639A2 for MerCruiser stern drives equipped with a drive-unit shift cable. This flexible, ribbed composite bellows helps seal the shift cable entry point against water; it is a dedicated shift cable entry-point bellows, not a U-joint bellows or an exhaust bellows.

Match the application

Applies to MerCruiser stern drives that use a drive-unit shift cable. Identify the part by its shift cable entry-point location and reference number rather than by the ribbed shape alone.

Workshop sequence

General workshop guidance only; use the service procedure for your exact drive or engine configuration.

  1. Confirm that your MerCruiser stern drive uses a drive-unit shift cable and match the bellows to the shift cable entry point before disassembly.
  2. Clean and inspect the mating surfaces at the shift cable entry point and along the cable routing path so the new bellows seats evenly.
  3. Position and secure the bellows without twisting or pinching the ribbed composite body, following the service procedure for your specific MerCruiser drive configuration.
