14. Independent Product Description

This rugged marine reverse bevel gear is a reliable aftermarket replacement for multiple Nissan 4‑6HP outboard motors including 2002 NSF4A2, NSF5A, NS5B, NSF5A2, NSF5B, NSF6B and MFS6A2. It helps restore reverse‑gear function for worn lower‑unit transmission assemblies in marine working conditions.

Built from wear‑resistant quenched alloy steel, this component undergoes accurate CNC machining alongside thorough heat‑treatment steps. Its solid construction maintains steady structural rigidity under continuous torque loads and salt‑spray marine surroundings. Hardened gear teeth resist chipping and scuffing during frequent forward‑reverse gear shifts.

Every 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 common gear‑case troubles such as reverse gear slipping, grinding noise, choppy power transmission and heavily worn‑down tooth surfaces. Swapping out the aged reverse gear restores stable reverse‑gear performance inside your outboard gear case. Be sure to refer to the official factory service manual for proper mounting and gear‑oil top‑up. Once assembled correctly, your Nissan outboard will deliver reliable power‑output performance on open water.

Fit on: TOHATSU/NISSAN 4, 5, 6 HP
