Jabsco 17935-0001-B Neoprene Impeller, 12 Blade
The Jabsco 17935-0001-B is a genuine Jabsco flexible impeller with a neoprene impeller, supplied as a single impeller kit, bulk packed. It has 12 blades, a 3-3/4 in diameter and a 2-1/2 in width, with a 1 in spline drive, brass insert. As it turns inside the offset pump body, the blades bend and straighten, drawing liquid in and pushing it out, which is what makes a flexible impeller pump self-priming. It is listed for Jabsco 6400 and 7420 series engine cooling pumps and the 17810-1000 engine cooling pump. The impeller itself is Jabsco 17935-0001.
Neoprene is the general purpose compound for water, raw water cooling and mildly abrasive liquids. Impellers are wear parts. Replace one when blades are cracked, torn or have taken a permanent set in the curved position, when the pump is slow to prime, or after it has run dry even briefly. Lubricate the new impeller with a little water pump grease before fitting it, and fit a new end cover gasket or O-ring at the same time.

Frequently Asked Questions
Q: Why is my new impeller hard to fit?
The blades need to fold the right way. A little grease on the blades and turning the shaft in the running direction as you push helps.
Q: Which way should the blades bend?
They bend back against the direction of rotation as the impeller is pushed into the body. Turning the shaft in the running direction while pushing makes this easy.
Q: How long does an impeller last?
It depends on hours, temperature and what is being pumped. Many owners replace it every season or at a set number of running hours as insurance.
Q: What causes blades to break off?
Running dry is the main cause. Broken pieces can travel downstream and block coolers or strainers, so find every piece.
