4-Pack Polyurethane Impeller Kit 6303-0007-P With O-Rings - Replacement For Jabsco Ballast Pumps
About this item
Wakeboard and ski boat owners, this 4-pack of polyurethane impellers is exactly what you need to keep your ballast pumps running smoothly!
The 6303-0007-P part number replaces Jabsco 18220 series impellers and works with Johnson Ultra Ballast Pumps and other similar systems.
The green polyurethane material is specifically chosen for water applications - it has excellent wear resistance and handles continuous immersion without degrading.
The six-blade design with 2-inch diameter and 7/8-inch width generates strong water flow for efficient ballast tank filling and draining.
What's great about this kit is you get everything needed for maintenance: the impellers themselves, plus O-rings and glycerin lubrication for proper installation.
The single flat D drive design ensures positive engagement with the motor shaft, preventing slippage and maintaining efficient power transfer.
Having four impellers on hand means you're prepared for multiple pump services or can help out fellow boaters when their impellers fail.
Ballast pump impellers do wear out over time, especially with frequent use, so keeping spares onboard prevents ruined days on the water.
The polyurethane construction is more durable than rubber in these applications, lasting longer between replacements.
Installation is straightforward - just make sure to lubricate with the included glycerin before installation to prevent dry start damage.
