Jabsco Ballast Pump Impeller Kit, 6-Blade, Urethane, 2 in Diameter, Single Flat Drive

Overview

The Jabsco 6303-0007-P is a urethane impeller kit for certain Jabsco flexible impeller ballast and water transfer pumps that use a 6-blade, single flat drive impeller with a 2 inch diameter, 7/8 inch width, and 5/16 inch shaft size.

This version uses a urethane impeller with a plastic insert. Those details matter when you are matching a replacement to the pump already on board, since blade count, drive style, diameter, width, and shaft dimensions all need to line up with the existing pump body and shaft.

For boat owners replacing a worn ballast pump impeller before the season or carrying a spare on board, this kit is aimed at keeping water moving without guessing at fit. It suits applications where the pump is already built around this exact impeller profile, including Jabsco ballast pump setups that call for 6303-0007-P.

Key features

• 6-blade urethane impeller sized at 2 inch diameter with 7/8 inch width and 5/16 inch shaft size
• Single flat drive for pumps that use this shaft and hub arrangement
• Plastic insert construction as specified for this kit
• Replacement fit for Jabsco ballast pump applications that call for part number 6303-0007-P
• Useful as a scheduled service spare for ballast and water transfer systems that depend on a flexible impeller pump

Compatibility and fit

Fit comes down to the impeller profile, not just the brand name on the pump. Before ordering, match the existing impeller by part number and confirm the 6-blade layout, single flat drive, 2 inch diameter, 7/8 inch width, and 5/16 inch shaft size. This kit is used in Jabsco ballast pump applications and is also listed for Ballast SuperKing service use.

It is a practical match for wake and ski boat ballast systems that already use this impeller profile. On those boats, the impeller is a wear item, so replacing it before it hardens, takes a set, or loses prime helps keep fill and drain times closer to normal.

Installation and service

When replacing the impeller, remove the pump end cover and pull the old impeller from the hub rather than prying against the pump body. Greasing the new impeller during installation helps it slide into the bore and gives it some protection during the first prime. Once the cover and seal are back in place, the pump can be returned to service.

On boats that see frequent ballast cycling, keeping a spare impeller on board makes sense. This product is a good fit for owners who already know their pump uses 6303-0007-P and want a direct replacement that matches the original blade count, dimensions, and drive style.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
