The Jabsco 22040-0701S is a genuine Jabsco bronze flexible impeller seawater pump designed to mount directly to specific marine diesel engines and circulate raw water through the cooling system. It is a flange-mounted, engine-driven pump with a large size 270 neoprene impeller, built for the steady, high-volume cooling flow that heavy-duty diesel engines need.
The bronze pump body stands up to constant salt water exposure, and the flexible impeller design self-primes and handles small debris better than rigid impeller designs. As a direct replacement for the original engine pump, it lets you restore full cooling performance without modifying mounts or plumbing, which reduces downtime for commercial and recreational vessels alike.

Frequently Asked Questions
Q: Is this the same pump as 22040-0501?
No. Both are size 270 bronze engine pumps, but they are built for different engine installations. Match the number on your pump plate before ordering.
Q: How often should the impeller be replaced?
Most operators replace it every season or at each major engine service, and immediately if the engine starts running warmer than normal.
Q: Can the pump run without water?
Only for a few seconds. The impeller depends on water for lubrication, so open the seacock before starting the engine.
Q: What is the best way to extend pump life?
Keep the seawater strainer clean, replace the impeller on schedule, and flush with fresh water when laying up the boat.
