This heavy‑duty outboard gear set includes reverse gear OE 6N0‑G5571‑00‑00, along with matching forward gear and pinion gear. It cross‑references part numbers 6N0‑G5560‑00 and 6N0‑G5551‑00. It is a direct aftermarket replacement designed for Yamaha 2‑stroke 8HP outboard lower unit gearbox.
Built using wear‑resistant quenched alloy steel, each gear undergoes precision CNC machining and standardized heat‑treatment processes. The gear set offers high structural stiffness and outstanding fatigue resistance. It stands up to frequent shifting impact and heavy cyclic loads during long‑hour marine operation. It keeps stable meshing performance under salt‑spray and harsh marine environments, minimizing gear abrasion, tooth chipping and abnormal shifting knocking noise.
Gear tooth profiles, splines and all mating dimensions strictly comply with OEM tolerance standards. Accurate assembly can be finished without extra trimming or reworking.
As a practical aftermarket service‑grade spare, this gear set resolves typical lower‑unit issues including stiff shifting, gear slipping, knocking sound and power transmission loss. It restores reliable forward‑reverse shifting performance for your outboard motor. Remember to inspect and refill gear oil after installation. Follow factory service manual for proper fitting, so your Yamaha 8HP outboard can deliver stable power output on water.
