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

Overview

The Jabsco 6303 Impeller Kit is a replacement flexible impeller kit for compatible Jabsco marine pumps where a 6-blade, single-flat-drive impeller is required.

This impeller size is commonly listed as 2 in. diameter by 7/8 in. wide with a 5/16 in. shaft diameter, also identified as Jabsco profile H. Those measurements matter because a flexible impeller must match the pump body, shaft, and drive style closely to maintain proper water movement and avoid premature wear.

The range is offered in neoprene and nitrile materials, giving boat owners a way to match the impeller material to the fluid being moved. Neoprene is the standard choice for water-pumping duties, while nitrile is used where oil, fuel contamination, or waste-handling conditions may be present.

Key features

• 6-blade flexible impeller format for compatible marine pump service and seasonal replacement work.
• 2 in. diameter, 7/8 in. width, and 5/16 in. shaft diameter help confirm fit before installation.
• Single flat drive matches pumps that use this shaft engagement style.
• Profile H sizing gives a useful cross-check when comparing the existing impeller to Jabsco identification charts.
• Material options cover common onboard pumping needs, from clean water movement to more contaminated fluid transfer.
• Suitable for maintenance planning on boats where carrying a spare impeller reduces downtime during cruising, fishing, or dockside service.

Variants

This Jabsco 6303 impeller kit is offered in two material configurations.

The impeller dimensions, 6-blade layout, single flat drive, and profile H identification are consistent across the two variants. The key difference is the impeller material, which affects the type of onboard pumping job the kit is suited for.

• 6303-0001-P: Neoprene material. This version is used for water-pumping applications such as compatible shower drain, ballast, transfer, and general marine water pumps.
• 6303-0003-P: Nitrile material. This version is used where the pumped fluid may include oil contamination, fuel contamination, or marine toilet waste material.

Compatibility and fit

Before installation, compare the removed impeller with the replacement by checking blade count, outside diameter, width, shaft diameter, and drive shape. A close match is important because even a small mismatch can reduce pump output or place extra load on the pump.

This kit is a practical service part for boat owners maintaining compatible Jabsco flexible impeller pumps used around the vessel, including water transfer, shower drain, ballast, bilge-related, and waste-handling systems where the pump model calls for this profile and material.

Installation and care

Inspect the pump chamber, cover plate, gasket surfaces, and shaft area when replacing the impeller. Any scoring, debris, hardened rubber pieces, or a damaged seal surface should be addressed before the pump is put back into service.

Flexible impellers should not be run dry. After replacement, confirm that the pump is primed and moving fluid normally, then check for leaks around the cover and fittings. Keeping a spare impeller kit on board is sensible for boats that see regular use in saltwater, long weekends away from the dock, or cruising where pump service parts may not be easy to find.

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.
