Jabsco 6987-0000 Stainless Steel Shaft
The Jabsco 6987-0000 stainless steel shaft is the factory replacement part for a family of marine diesel engine raw water cooling pumps used across several 6- and 8-cylinder inline diesel engines. It is the driven shaft that carries the pumping element and transmits torque from the motor, pulley or gearbox. The wear points are the seal journal, where the shaft rides against the lip seal or mechanical seal face, and the drive end, where a worn keyway or flat lets the coupling or pulley slip.
It is supplied as a direct, drop-in replacement, made to the same material and dimensions as the original Jabsco part, so no fitting or modification is needed. Replacing it as a matched pair with its mating gasket or seal, rather than on its own, is the more reliable repair when the pump has been in service for several seasons.

Frequently Asked Questions
Q: How often does this part need replacing?
That depends on run hours and duty cycle rather than age alone. Replace it at the first sign of reduced performance, leakage or noise rather than waiting for a full failure.
Q: Can I install this myself?
Yes. It is a like-for-like replacement for the original Jabsco part and needs no modification, though you should follow the torque and orientation of the part it replaces.
Q: Do you carry the rest of the service kit for this pump?
Yes, the related gaskets, seals and wear items for this pump family are stocked separately. Send us your pump data plate and we can point you to the full kit.
Q: Will this fit my pump?
It is the factory part for 6980-3100 series engine cooling pumps. If your pump carries a different model number, send us a picture of the data plate and we will confirm before you order.
