Independent Product Description
This sturdy marine front bevel gear works as a quality aftermarket replacement matched to OE number 350‑64010‑0. It is purpose‑built for Nissan 9.9HP outboard models NS9.9B2, NS9.9D and NS9.9D2.
Made from premium quenched alloy steel, this gear goes through precise CNC machining and complete industrial heat‑treatment. It brings solid surface hardness, structural toughness and great wear‑resistant performance. The part copes with continuous torque loads and harsh salt‑spray marine environments well. It also lowers risks of tooth chipping, scuffing and deformation during regular forward‑reverse gear shifts.
All structural sizes and mounting interfaces follow OEM requirements closely, enabling fast, accurate and trouble‑free drop‑in fitting. This replacement solves frequent lower‑unit troubles such as forward gear slipping, strange grinding noises, uneven power transfer and heavily worn gear teeth.
Replacing your old, worn‑out front gear with this unit restores reliable forward‑drive performance for the outboard lower unit. Use suitable gear oil and complete assembly per official factory instructions. Correct fitting ensures long‑term stable operation for your outboard under real marine working conditions.
