14. Independent Product Description
This tough marine reverse gear acts as a solid aftermarket substitute matching OEM part numbers 350‑64030‑00‑00 and 362‑64030‑00‑00. It is custom‑built for Tohatsu, Nissan and Mercury NS15B2 outboard motors manufactured in 2002 and earlier, widely used during transmission and water pump overhaul work.
Crafted from wear‑resistant quenched alloy steel, this component receives precise CNC machining plus rigorous heat‑treatment procedures. Such solid build lets it maintain stable structural rigidity amid heavy shift loads and salt‑spray marine environments. Hardened gear teeth stand up against chipping and abrasion during frequent forward‑reverse gear changes.
Every inner bore size and spline dimension aligns closely with OEM tolerance standards. Installers can finish fast, accurate fitting, and no trimming or secondary rework is necessary.
This practical service‑grade aftermarket component fixes typical gearbox issues, including jerky reverse engagement, grinding gear sounds, reverse slipping and tooth surface wear. Swapping out the worn reverse gear brings back smooth reverse function for your outboard lower unit. Make sure you follow the official factory service manual for proper mounting, gear‑oil refill and related water‑pump inspection. Once fitted correctly, your outboard will offer dependable shifting performance on open water.
