Independent Product Description
This robust marine reverse bevel gear C acts as a high‑quality aftermarket replacement. It matches OE references 3C7‑64093‑0 and 3T1‑64093‑0, and is custom‑built for Nissan 90‑115HP outboard engines.
Manufactured from premium quenched alloy steel, this gear adopts precise CNC machining and integrated industrial heat treatment. It delivers outstanding surface hardness, structural toughness and anti‑wear properties. The component handles sustained high‑torque operation and severe salt‑laden marine conditions with ease. It also efficiently avoids tooth chipping, surface scuffing and structural deformation during frequent forward and reverse gear shifts.
Every structural size and mounting interface fully adheres to OEM specifications, which allows quick, precise and hassle‑free drop‑in installation. This replacement part effectively fixes typical lower unit faults, including reverse gear slippage, unusual grinding sounds, inconsistent power delivery and excessive gear tooth wear.
Swapping out your worn or aged reverse gear with this unit can fully recover steady reverse gear functionality for your outboard lower unit. Always refill with qualified gear oil and follow official factory guidelines for standard assembly. Proper installation guarantees durable and dependable operational performance during all marine applications.
This part also can be used in the following motors:
