14. Independent Product Description

This heavy‑duty marine gear kit includes pinion gear 346‑64020‑00, forward gear 346‑64010‑00 and reverse gear 346‑64030‑00. It serves as direct aftermarket replacement for Tohatsu 25HP gasoline outboard lower drive gearbox.

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. Users can complete accurate assembly without trimming or secondary reworking.

As a reliable aftermarket service‑grade spare, this gear set resolves common lower‑unit troubles such as stiff shifting, gear slipping, knocking noise and power transmission loss. It restores dependable forward‑reverse shifting performance for your gasoline outboard motor. Inspect and refill gear oil after installation. Follow factory service manual for proper fitting, so your Tohatsu 25HP outboard can transmit power reliably on open water.
