14. Independent Product Description
This heavy‑duty marine bevel gear kit includes pinion bevel gear 350‑64020‑00, forward gear 350‑64010‑00 and reverse gear 350‑64030‑00. It acts as a reliable aftermarket replacement for Tohatsu 9.9HP, 15HP and 18HP 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 achieves high structural stiffness and superior fatigue resistance. It withstands frequent shifting impact and cyclic heavy loads during long‑duration marine operation. It maintains 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. Accurate assembly can be completed without trimming or secondary rework.
As a practical aftermarket service‑grade spare, this gear set resolves common 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 Tohatsu outboard can transfer power reliably on open water.
