Description

The Jabsco 2.039 Impeller is a direct replacement raw water pump impeller designed for marine engines equipped with compatible Jabsco pump assemblies. This impeller is responsible for circulating cooling water through the engine, maintaining proper operating temperature and preventing overheating.

Manufactured from high-quality marine-grade neoprene rubber, this impeller provides excellent flexibility, durability, and resistance to wear in both freshwater and saltwater environments. Replacing a worn impeller restores proper cooling performance and helps protect your engine from costly damage.

This impeller is commonly used across Jabsco raw water pump systems, making it a key maintenance item for reliable marine engine operation.
