🔌 Function

The gear set transfers torque through the sterndrive at the designed reduction ratio.

⚠️ Common Signs of Failure

  • Abnormal drive noise
  • Metallic debris in gear oil
  • Chipped or pitted teeth
  • Excessive gear backlash
  • Drive vibration
  • Loss of forward or reverse propulsion
  • Overheating caused by incorrect bearing preload

🛠️ Service Notes

  • Gear sets are supplied as a matched set and must be fitted complete — never run a new gear against a used mate, and keep the set together as it was delivered
  • Setting up requires the shimming, backlash and tooth contact pattern checks in the workshop manual for your engine and drive, together with the proper measuring and pressing tools; this is not a fit-and-hope job
  • Establish why the old set failed before assembly — debris, a collapsed bearing or oil starvation will destroy the new gears just as quickly
  • Renew the bearings, seals and locking hardware at the same time, and flush the housing thoroughly so no metal debris is left in it
  • Fill with the oil specified for your drive, then check the oil early in service for signs of abnormal bedding-in debris
