14. Independent Product Description
This rugged marine pinion gear works as a functional aftermarket replacement compatible with OEM part numbers 350‑64020‑0, 350640200 and 350640200M. It matches Tohatsu and Nissan two‑stroke and four‑stroke outboard motors within the 9.9‑horsepower to 18‑horsepower range.
Built from wear‑resistant quenched alloy steel, this component undergoes accurate CNC machining alongside thorough heat‑treatment steps.
Its solid construction keeps steady structural rigidity under continuous torque loads and salt‑spray marine surroundings. Hardened bevel gear teeth hold up against chipping and scuffing during repeated forward‑reverse gear shifts.
Each shaft‑hole measurement and spline dimension closely meets OEM tolerance benchmarks. Fitters can complete quick, exact installation, and no trimming or secondary rework is necessary.
This practical service‑grade aftermarket part resolves frequent gear‑case troubles. These include choppy power transmission, grinding gear noises, gear jumping and heavily worn‑down tooth surfaces. Replacing your worn‑out pinion gear brings back stable power transfer inside your outboard lower unit. Always refer to the official factory service manual for correct mounting and gear‑oil refilling. Once assembled properly, your Tohatsu or Nissan outboard will deliver consistent power‑output performance on open water
