14. Independent Product Description
This rugged marine pinion bevel gear serves as a capable aftermarket replacement matching OEM part numbers T5‑03000003 and 16138. It fits Tohatsu and Nissan MFS series outboard motors covering MFS2, MFS2.5, MFS3.5, MFS4, MFS5 and MFS6 models.
Built from wear‑resistant quenched alloy steel, this component goes through accurate CNC machining alongside thorough heat‑treatment steps. Its sturdy physical build keeps steady structural rigidity under continuous torque loads and salt‑spray marine surroundings. Hardened bevel gear teeth hold up against chipping and scuffing during frequent forward‑reverse gear shifts.
Every shaft‑hole measurement and spline dimension closely follows OEM tolerance benchmarks. Fitters can complete quick, exact installation, and no trimming or secondary rework is necessary.
This practical service‑grade aftermarket part resolves common gearbox troubles, such as choppy power transmission, grinding gear noise, gear jumping and worn‑out tooth surfaces. Swapping out the aged pinion bevel gear restores stable power transfer inside your outboard lower unit. Be sure to refer to the official factory service manual for proper mounting and gear‑oil top‑up. Once assembled correctly, your Tohatsu or Nissan outboard will deliver reliable power‑output performance on open water.
