The Johnson Pump 09-1026B-1 is a genuine, high-performance flexible marine impeller kit designed primarily for engine cooling and general water-transfer duties in F4-series pumps.This 6-blade model is manufactured from Johnson's proprietary MC97 rubber compound (an advanced EPDM blend), which provides a significantly extended service life compared to traditional neoprene by resisting thermal breakdown and stabilizing the blades under pressure. Dimensionally, the impeller features an outer diameter of 50.8 mm (2.00 inches), a width of 22.0 mm (0.87 inches), and a 12.7 mm (0.50 inch) inner diameter designed for a slotted pin drive shaft setup. Because engine cooling is so vital to preventing catastrophic boat engine failures, this specific kit serves as a highly reliable direct OEM replacement for various Volvo Penta, Perkins, and Westerbeke engines, while seamlessly crossing over to replace popular competitors like the Jabsco 673-0001.
