The Jabsco 22645-0000 is a genuine Jabsco mechanical seal assembly for 1 inch Jabsco engine cooling pumps. The mechanical seal keeps raw water from leaking along the pump shaft, protecting the bearings and the engine drive while the pump circulates cooling water.
When the seal wears, water drips from the pump's weep hole or around the shaft, and salt water can quickly damage bearings and nearby engine components. Replacing the seal as soon as a leak appears, or whenever the pump is overhauled, keeps the cooling pump tight and dependable.

Frequently Asked Questions
Q: What does water from the weep hole mean?
It means the shaft seal is leaking. The weep hole lets water escape before it reaches the bearings, so replace the seal soon.
Q: Should the impeller be replaced at the same time?
Since the pump is already apart, it is a good time to fit a new impeller, cover gasket and wear plate if needed.
Q: Is special care needed installing a mechanical seal?
Yes. Keep the seal faces clean and undamaged, and follow the pump manual for seating depth and lubrication.
Q: How do I confirm it fits my pump?
Check the model number on your pump plate against its parts list, or send us a photo and our team will confirm.
