Fit Engine: 40HP E40X 2-Stroke X series 40XMH
This brand‑new aftermarket connecting rod kit covers OE references 66T‑11650‑00, 66T‑11650‑01 and 66T‑11650‑11 for Yamaha 40HP two‑stroke X‑series 40XMH outboard motors. Manufactured to original dimensional standards, it delivers accurate fitment for marine engine overhaul. Forged from high‑strength quenched alloy steel, this unit goes through precision CNC machining and strict heat‑treatment processes. It features high structural rigidity and superior fatigue resistance to handle repeated cyclic loads during long‑hour marine operation. It maintains consistent mechanical performance under high‑humidity and salt‑corrosive marine conditions, resisting seawater‑triggered wear and component aging. Every machined surface meets strict industrial tolerances, enabling fast and precise bolt‑on installation without extra trimming. This replacement part fixes frequent engine issues including rough running, metallic knocking noise and power loss, normally brought on by original connecting‑rod abrasion, bending and metal fatigue. It restores steady power output for your outboard, meanwhile protects pistons and other internal engine components from secondary friction damage. Professional installation together with periodic lubrication will help extend the service life of your Yamaha outboard motor.
