This heavy‑duty marine gear kit includes reverse gear OE 3B2‑64030‑00, matching forward gear 3B2‑64010‑00 and pinion bevel gear 3B2‑64020‑00. It is a reliable aftermarket replacement compatible with part numbers 3B2‑64030‑1, 3B2640300, 3B2640301 and 3B2640300M for Tohatsu and Nissan outboard lower‑unit gearbox.
Built from 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 practical aftermarket service‑grade spare, this gear set resolves common lower‑unit troubles such as stiff reverse engagement, gear slipping, knocking noise and power transmission loss. It restores smooth forward‑reverse shifting performance for your outboard motor. Inspect and refill gear oil after installation. Follow factory service manual for proper fitting, so your Tohatsu / Nissan outboard can transmit power reliably on open water.
