This heavy‑duty marine reverse bevel gear serves as a dependable aftermarket replacement for Tohatsu and Nissan high‑horsepower outboard engines covering model years 2010, 2011 and 2012, including MD115A2, MD90B, NSD115A2 and NSD90B. It brings back proper reverse‑gear operation for heavily‑loaded lower‑unit transmission assemblies exposed to salt‑spray marine environments.

Built from wear‑resistant quenched alloy steel, this component goes through precise CNC machining and complete heat‑treatment procedures. Its robust structure retains stable rigidity under sustained high‑torque loads. Hardened gear teeth stand up to chipping and scuffing during frequent forward‑reverse gear shifts.

All shaft‑hole and spline dimensions follow OEM tolerance standards. Fitters can finish quick, accurate installation without trimming or secondary modification.

This service‑grade aftermarket part fixes typical gear‑case issues including reverse gear slipping, grinding noise, uneven power transfer and heavily worn gear teeth. Replacing the worn reverse gear restores consistent reverse‑gear performance inside the gear case. Always follow the official factory service manual for proper fitting and gear‑oil refill. When correctly assembled, your outboard will provide steady power output during on‑water operation.

This part also can be used in the following motors:
