Independent Product Description
This robust marine water pump impeller serves as a reliable aftermarket replacement matching OEM part numbers 646‑44352‑00, 646‑44352‑01‑00 and aftermarket reference T2‑03000100. It is purpose‑built for Yamaha two‑stroke 2HP outboard variants 2A, 2B and 2C.
Fabricated from high‑quality marine‑grade rubber compound, this impeller offers good elasticity, outstanding tear‑resistance and solid salt‑water anti‑corrosion performance. Blades keep stable geometry under continuous rotation. Adhering to regular service cycles will greatly reduce blade cracking, scuffing and premature wear in harsh marine boating environments.
Every structural dimension and inner‑bore specification strictly meets OEM standards, enabling quick, accurate and hassle‑free drop‑in fitting. This replacement component resolves typical cooling‑system troubles such as engine overheating, insufficient cooling‑water flow, weak water discharge and worn‑out impeller blades.
Replace your aged or damaged impeller with this unit to restore stable cooling‑water circulation for your Yamaha outboard motor. Apply dedicated water‑pump lubricant during assembly and never run the motor without water supply. Correct fitting guarantees long‑term dependable cooling performance under real‑world marine working scenarios.
