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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e6-blade flexible impeller format for compatible marine pump service and seasonal replacement work.\u003c\/li\u003e\n\u003cli\u003e2 in. diameter, 7\/8 in. width, and 5\/16 in. shaft diameter help confirm fit before installation.\u003c\/li\u003e\n\u003cli\u003eSingle flat drive matches pumps that use this shaft engagement style.\u003c\/li\u003e\n\u003cli\u003eProfile H sizing gives a useful cross-check when comparing the existing impeller to Jabsco identification charts.\u003c\/li\u003e\n\u003cli\u003eMaterial options cover common onboard pumping needs, from clean water movement to more contaminated fluid transfer.\u003c\/li\u003e\n\u003cli\u003eSuitable for maintenance planning on boats where carrying a spare impeller reduces downtime during cruising, fishing, or dockside service.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eVariants\u003c\/h6\u003e\u003cp\u003eThis Jabsco 6303 impeller kit is offered in two material configurations.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e6303-0001-P: Neoprene material. This version is used for water-pumping applications such as compatible shower drain, ballast, transfer, and general marine water pumps.\u003c\/li\u003e\n\u003cli\u003e6303-0003-P: Nitrile material. This version is used where the pumped fluid may include oil contamination, fuel contamination, or marine toilet waste material.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eBefore 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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch6\u003eInstallation and care\u003c\/h6\u003e\u003cp\u003eInspect 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.\u003c\/p\u003e\u003cp\u003eFlexible 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.\u003c\/p\u003e","brand":"Jabsco","offers":[{"title":"Neoprene","offer_id":52581967855797,"sku":"QBP265684-V1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Nitrile","offer_id":52581967888565,"sku":"QBP265684-V2","price":38.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1334501_qbp265684.png?v=1780201883","url":"https:\/\/www.qualityboatparts.com\/products\/qbp265684","provider":"Quality Boat Parts","version":"1.0","type":"link"}
