Independent Product Description
This heavy‑duty marine forward bevel gear serves as a dependable aftermarket replacement matched to OE part number 350‑64010‑0. It is custom‑made for Tohatsu, Nissan and Mercury outboard motors at 9.9HP, 15HP and 18HP, supporting both two‑stroke and four‑stroke setups.
Constructed from high‑grade quenched alloy steel, this gear receives precise CNC machining and full industrial heat‑treatment. It gains great surface hardness, solid structural toughness and strong wear‑resistant properties. The component handles sustained torque loads and harsh salt‑laden marine conditions very well. It also lowers risks of gear tooth chipping, scuffing and deformation during frequent forward‑reverse gear shifts.
All structural sizes and mounting interfaces strictly follow OEM specifications, enabling quick, accurate and hassle‑free drop‑in fitting. This replacement part resolves typical lower‑unit faults, including forward gear slippage, unusual grinding noises, inconsistent power transfer and heavily worn gear teeth.
Swap out your worn‑out forward gear with this unit, and you can restore stable forward‑drive performance for the outboard lower unit. Always use qualified gear oil and finish assembly following official factory guidelines. Proper fitting guarantees durable and reliable working performance during all marine‑based operations.
