14. Independent Product Description
This heavy‑duty outboard gear set features pinion gear OE 6N0‑G5551‑00 and short‑form part number 6N0‑G5551. It cross‑references forward gear 6N0‑G5560‑00 and reverse gear 6N0‑G5571‑00‑00. It acts as direct aftermarket replacement for Yamaha 6HP and 8HP two‑stroke outboard lower unit gearbox.
Built using wear‑resistant quenched alloy steel, every gear component receives precision CNC machining and standardized heat‑treatment. The whole set delivers high structural stiffness and excellent fatigue resistance. It withstands frequent shifting impact and cyclic heavy loads during extended marine operation. It maintains stable gear meshing performance under salt‑spray and rough boating conditions, reducing gear abrasion, tooth chipping and abnormal shifting knocking noise.
All gear tooth profiles, splines and mating dimensions strictly comply with OEM tolerance criteria. Users can complete accurate assembly without trimming or secondary reworking.
As a practical aftermarket service‑grade spare, this gear set fixes common lower‑unit troubles such as stiff shifting, gear slipping, knocking noise and power transmission loss. It restores normal forward‑reverse shifting function for your outboard motor. Inspect and refill gear oil after installation. Follow factory service manual for proper fitting, so your Yamaha outboard can transmit power reliably on open water.
