Jabsco Ballast King Replacement Impeller 23095-0007, 24-Pack Bulk

This is the genuine Jabsco replacement impeller for the Ballast King ballast pump, and this listing is the bulk 24-pack. If you turn wrenches on wake boats for a living, you already know where this part lives on the shelf. The impeller is the one thing inside a Ballast King that's guaranteed to wear out, and having a full box of them on hand means you're never the shop that has to tell a customer to come back next week.

Here's what the Ballast King does. It's a reversible flexible impeller pump, so it fills the ballast tanks and then drains them by spinning the same impeller in the other direction. That flexible impeller is the heart of the whole thing. Its soft vanes flex against the pump housing to move a big volume of water fast, which is exactly what you want when a rider is standing on the platform waiting for the tank to top off. Every fill and every drain flexes those vanes. Over a season of hard use, they take a beating.

Impellers don't last forever, and on a ballast pump they take more abuse than most. Run one dry for even a few seconds and the vanes cook. Suck a bit of grit or a stray zip tie through the pump and you'll nick a vane. And even with good care, the rubber takes a set over time and loses the snap that gives you strong flow. When a customer complains their tanks are filling slow, or the pump sounds like it's working harder than it used to, the impeller is the first thing you pull. Nine times out of ten, that's the fix.

One thing to be clear about up front. This is the impeller only. It does not come with an O-ring or lubricant. That's normal for how these ship in bulk, but it means you'll want to keep a supply of matching cover O-rings and a tube of impeller grease on the bench alongside this box. Don't reuse a tired O-ring on a fresh impeller and expect a dry seal. Do it right the first time.

Install is straightforward if you've done a flexible impeller before. Pop the pump cover, work the old impeller out, and inspect the housing and cover plate for scoring while you're in there. Coat the new impeller's vanes with a marine impeller lubricant before it goes in, seat it with the vanes bending the correct way for rotation, drop in a fresh O-ring, and button it up. Prime the pump before you run it. That grease matters, because the first few revolutions on a dry impeller are where most of the damage happens.

The 24-pack exists for a reason. This is a dealer and service quantity, sized for the shop that's rebuilding Ballast King pumps all season, the wake-boat dealer stocking parts for warranty and service work, or a rental and lesson fleet that runs their boats hard enough to go through impellers on a schedule. Buying them 24 at a time means you're never chasing singles at the worst possible moment, and your cost per unit comes down. If you only need one impeller for your own boat, this bulk pack is more than you need, but for anyone servicing these pumps regularly it's the right way to buy.

Fitment is the Jabsco Ballast King family. These impellers are the correct replacement for the 22610 series pumps, including the 22610-9427 this listing calls out. If you're not sure which pump is on a given boat, match the pump's part number against the Ballast King range before you order, and remember the impeller itself is the same genuine Jabsco purple part across the series. When you want the pump moving water the way it did when it was new, a fresh genuine impeller is the cheapest, fastest way to get there.
