14. Independent Product Description
This heavy‑duty outboard gear kit includes forward gear OE 646‑45560‑00, matched pinion gear 646‑45551‑00 and reverse gear 646‑45570‑00. It serves as direct aftermarket replacement for Yamaha 2HP two‑stroke outboard lower unit connected to propeller shaft.
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 extended 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. Accurate assembly can be completed without trimming or secondary reworking.
As a reliable aftermarket service‑grade spare, this gear set resolves common lower‑unit faults such as stiff shifting, gear slipping, knocking noise and power transmission loss on propeller shaft system. It restores dependable 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
