Those dimensions are the key fit points on a boat, because they determine how the impeller seats in the pump bore and how the hub engages the shaft.\u003c\/p\u003e\u003cp\u003eThis profile is commonly used in raw-water cooling pumps and related water-moving pump setups where the original impeller matches the same dimensions and spline style. It is also associated with Jabsco 50410, 22110, and 23800 series crankshaft-driven pumps, so it is a practical service part for many inboard installations where pump access is tight and a correct spare matters.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e10-blade neoprene impeller for pump applications that match this blade count and profile\u003c\/li\u003e\n\u003cli\u003e2-1\/4 in. outside diameter and 2 in. width, which are critical measurements when matching an existing impeller\u003c\/li\u003e\n\u003cli\u003e5\/8 in. shaft size with spline-drive hub for compatible marine pump shafts\u003c\/li\u003e\n\u003cli\u003eBrass insert at the hub for the impeller profile used in this kit\u003c\/li\u003e\n\u003cli\u003eUseful as a scheduled service part and as a spare kept on board for raw-water pump maintenance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eCompatibility and fit\u003c\/h6\u003e\u003cp\u003eUse this kit where the old impeller matches the same outside diameter, width, shaft size, blade count, and spline-drive hub. That check matters more than engine brand alone, especially on older boats or repowered boats where pump history is not always clear.\u003c\/p\u003e\u003cp\u003eFor engine cooling service, a close dimensional match helps the pump prime correctly and maintain water flow without stressing the cover plate, cam, or shaft. If your current impeller has swollen, torn vanes, or a damaged hub, compare it before disposal so you can confirm the replacement profile against the pump in hand.\u003c\/p\u003e\u003ch6\u003eInstallation and service\u003c\/h6\u003e\u003cp\u003eWhen you fit a new impeller, inspect the pump cover and internal wear surfaces for grooves or scoring before closing the pump back up. A damaged cover face can cause poor prime or small air leaks that are easy to miss until engine temperature starts to climb.\u003c\/p\u003e\u003cp\u003eWet or lubricate the new impeller during installation so the vanes are not starting dry on first spin-up. On boats that run regularly, this is the sort of spare worth keeping in the engine room, particularly for coastal cruising, fishing boats, and small auxiliaries where a failed raw-water impeller can end the day quickly.\u003c\/p\u003e","brand":"Jabsco","offers":[{"title":"Default Title","offer_id":51554351317238,"sku":"APL331914","price":63.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0809\/6658\/2518\/files\/1104278_apl331914jpg.jpg?v=1787834485","url":"https:\/\/www.apollolighting.com\/products\/apl331914","provider":"Apollo Lighting","version":"1.0","type":"link"}
