Johnson Pump 09-1027B-10 F5 MC97 Impeller Kit 2.25 Inch Long, Replaces Jabsco 1210-0001, for Volvo Penta 4.3/5.0/5.7

The Johnson Pump 09-1027B-10 is an F5 MC97 impeller kit built for raw water pumps on Volvo Penta 4.3, 5.0, 5.7, and AQ engines, as well as Indmar 200 and Yanmar applications. The impeller is molded from MC97 compound, a material engineered specifically for cooling system service, and measures 2.25 inches in outer diameter, 1.24 inches wide, with a 12-spline inner diameter that drives directly off the pump shaft. The kit includes everything needed for a complete impeller change: the impeller itself, a gasket, an o-ring, and 7 grams of impeller lubricant to protect the vanes on startup.

This impeller is engineered for stable pressure delivery over time, a significantly longer service life than economy replacements, and excellent self-priming capability so the raw water pump draws water quickly at startup. The MC97 material is formulated to minimize swelling and reduce the fatigue-related cracking that causes premature impeller failure, while maintaining correct impeller dimensions for proper cooling flow and sufficient cooling directly at engine start up. It directly replaces Jabsco No 1210-0001 and is also compatible with several other Johnson Pump kit numbers, making it a straightforward like-for-like replacement for maintaining consistent raw water flow through the engine cooling system.
