Produced from superior-grade alloy steel, the YAMAHA 3HP Pinion Gear is shaped using high-precision CNC equipment to deliver exact tooth geometry, uniform pitch, and tight dimensional tolerances. Following machining, it receives specialized heat treatment that balances exceptional surface hardness with resilient core strength. This results in outstanding resistance to abrasion, shock loading, and fatigue, while ensuring smooth, low-friction engagement with adjacent gears to minimize operational noise and energy loss.
Engineered as a premium aftermarket substitute, the YAMAHA 3HP Pinion Gear (6L5-45551-00) conforms to original factory standards for perfect compatibility and performance. It fits the majority of Yamaha 3HP outboard models (both 2-stroke and 4-stroke configurations) widely used on compact fishing vessels, portable boats, inflatables, tenders, and small workboats. Whether installed during scheduled servicing, gear replacement, or full lower unit overhaul, this pinion gear restores crisp power transfer and enhances overall propulsion reliability.
Particularly robust in challenging marine conditions, the gear benefits from advanced material composition and protective surface finishing that offer strong defense against corrosion, saltwater erosion, and surface damage—when paired with appropriate lubrication and routine care. Every production batch undergoes comprehensive quality assurance checks, including detailed verification of tooth profile accuracy, surface quality, hardness values, and runout tolerance, delivering dependable consistency trusted by marine technicians and parts suppliers alike.
The YAMAHA 3HP Pinion Gear (6L5-45551-00) provides excellent value as a high-performance alternative to genuine OEM components. It combines proven durability, precise fit, and extended service life at a more economical price, helping boat owners and repair shops lower maintenance expenses, decrease repair turnaround time, and significantly prolong the service life of Yamaha 3HP outboard systems.
