Jabsco 18704-2000 Impeller
The Jabsco 18704-2000 is a genuine Jabsco replacement impeller. Jabsco uses this part number on specific models only, so match it against the parts list for the model number on your pump plate before ordering.
Impellers are wear parts. Replace one when the blades are cracked, torn or have taken a permanent set, when the pump is slow to prime, or after it has run dry even briefly. Lubricate a new flexible impeller with a little water pump grease before fitting it, and fit a new cover gasket or O-ring at the same time.

Frequently Asked Questions
Q: Which way should the blades bend?
They bend back against the direction of rotation. Turning the shaft in the running direction while pushing makes fitting easier.
Q: How long does an impeller last?
It depends on hours, temperature and what is being pumped. Many owners replace it every season.
Q: What causes blades to break off?
Running dry is the main cause. Find every broken piece so it does not block coolers or strainers.
Q: Should I grease the new impeller?
Yes, a light coat of water pump grease helps it survive the first dry seconds.
