Jabsco 30903-1000 Shaft Kit
The Jabsco 30903-1000 is a genuine replacement shaft kit for Jabsco 309-series flexible impeller raw water pumps. It is the driven shaft that carries the pumping element and transmits torque from the motor, pulley or gearbox, packaged with the small hardware needed to install it.
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: What else should I replace at the same time?
Since the pump is already open for this repair, inspect the nearby gasket, seal and fasteners and replace any that show wear so it does not need reopening soon after.
Q: Is this a genuine Jabsco part or an aftermarket copy?
It is a genuine Jabsco part, made to the original material and dimensional specification.
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.
