14. Independent Product Description
This heavy‑duty universal marine gear kit consists of pinion bevel gear B OE 3B2‑64020‑00, matching forward gear 3B2‑64010‑00 and reverse gear 3B2‑64030‑00. It works as direct aftermarket replacement for Tohatsu 6HP, 8HP, 9.8HP M, NS, F series outboard lower‑unit gearbox.
Built using wear‑resistant quenched alloy steel, each 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 long‑duration marine operation. It keeps stable bevel‑gear meshing performance under salt‑spray and harsh marine environments, effectively reducing 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 finish 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 smooth and 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.
