This heavy‑duty marine gear spare kit contains pinion gear, forward gear and reverse gear for Yamaha 2.5HP outboard Lower Drive 1 gearbox, matching OEM part numbers 6L5‑45551‑00, 6L5‑45560‑00 and 6L5‑45570‑00. It is a reliable aftermarket replacement for worn or damaged gears on 1989 3LF, 3SF and 1990 3LD, 3SD outboard units.
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 surroundings, 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 practical aftermarket service‑grade spare, this gear set solves typical lower‑unit faults including stiff shifting, gear slipping, knocking noise and power transmission loss. 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 outboard can transfer power reliably on open water.
