Product Description
The Vanguard 200 OHV 12V3520005F1CY1001 6.5 HP Engine with 6:1 Reduction Gearbox is a heavy-duty power unit engineered for applications requiring high torque, controlled output speed, and exceptional reliability. Built on the proven Vanguard 200 OHV platform, this model combines a robust 203cc commercial-grade engine with a precision-engineered 6:1 reduction box, delivering powerful low-RPM output ideal for machinery that demands smooth, consistent drive performance.
Designed with a cast-iron cylinder sleeve, heavy flywheel, and TransportGuard™ fuel/ignition shutoff, this engine offers long service life and reduced downtime. The addition of a 6:1 reduction gearbox transforms the engine’s high-speed output into slow, high-torque rotation.
