14. Independent Product Description
This heavy‑duty outboard gear kit includes 27‑tooth forward gear OE 646‑45560‑00, matched pinion gear 646‑45551‑00 and reverse gear 646‑45570‑00, also compatible with part number T2‑03000200. It works as direct aftermarket replacement for Yamaha 2HP 2MS two‑stroke outboard lower unit and propeller shaft system.
Built using wear‑resistant quenched alloy steel, each gear component undergoes precision CNC machining and standardized heat‑treatment procedures. The gear set delivers high structural stiffness and excellent fatigue resistance.
It withstands frequent shifting impact and cyclic heavy loads during long‑hour marine operation. It maintains stable gear‑meshing performance under salt‑spray and harsh marine environments, minimizing 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 finish accurate assembly without trimming or secondary reworking.
As a practical aftermarket service‑grade spare, this gear set fixes common lower‑unit troubles including stiff shifting, gear slipping, knocking noise and power transmission loss. It restores reliable forward‑reverse shifting performance 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.
