14. Independent Product Description
This heavy‑duty marine gear kit includes forward gear OE 646‑45560‑00, matching pinion gear 646‑45551‑00 and reverse gear 646‑45570‑00. It is a direct aftermarket replacement for Yamaha 2HP outboard lower unit gearbox.
Built using wear‑resistant quenched alloy steel, every gear component goes through precision CNC machining and standardized heat‑treatment procedures. The gear set features high structural stiffness and excellent fatigue resistance. It can withstand frequent shifting impact and cyclic heavy loads during long‑time marine operation. It keeps stable gear‑meshing performance under salt‑spray and harsh marine environments, effectively 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 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 2HP outboard can transfer power reliably on open water.
