The YP20G is powered by a 4-stroke engine that’s quieter, more powerful and consumes less fuel than comparable engines. It offers improved efficiency, increased reliability and quite operation, provides optimal heat dissipation, consistent performance during continuous use and long engine life, oil watch warning system (automatically shuts off before oil level is low and cannot be re-started until oil is added) which prevents engine damage and costly repairs while enhancing long-term durability, has a clean, efficient spark that ensures fast, easy starting. Low maintenance, reliable operation. Auto Decompression Automatically “opens” exhaust valve slightly to reduce initial backpressure when starting making manual starting effortless. Pumps up to 600 L/min (36,000 L/hr) through a two-inch port. Impeller and volute case are cast iron for greater strength and durability; and they withstand wear from grit, sand, silt, etc. Durable carbon-ceramic seats are easy to replace and they reduce abrasion for long pump life. Standard National Pipe Thread (NPT) fittings connect easily with the suction and discharge hoses. Sturdy tubular Frame for added protection and easy carry. Large muffler for quiet operation.
