Jabsco 18786-0001-24 Neoprene Impellers, Carton of 24
The Jabsco 18786-0001-24 is a genuine Jabsco neoprene flexible impeller, supplied as a carton of 24, with 9 blades, a 4-5/8 in diameter and a 3-1/2 in width on a 1 in epoxy double flat shaft hub. It is listed for the Jabsco 17540-0001 and 17540-0201 marine diesel engine cooling pumps.
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: Should I grease the new impeller?
Yes, a light coat of water pump grease helps it survive the first dry seconds.
Q: Why is my new impeller hard to fit?
The blades must fold the right way. Grease and turning the shaft as you push both help.
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.
