14. Independent Product Description
This heavy‑duty marine gear kit includes reverse gear, matching forward gear and pinion bevel gear for Tohatsu M, NS, MFS, NSF 6HP, 8HP and 9.8HP two‑‑stroke and four‑stroke outboard lower‑unit gearbox. Corresponding OEM part number: 3B2‑64030‑00 and related cross‑reference numbers. It serves as a reliable aftermarket replacement for worn or broken original transmission gears.
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 practical aftermarket service‑grade spare, this gear set resolves common lower‑unit troubles such as difficult reverse gear engagement, 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 Tohatsu outboard can transmit power reliably on open water.
