It draws raw cooling water from the vessel’s seawater intake and circulates it through the engine’s raw-water cooling circuit, where it absorbs heat before being discharged overboard. The pump uses a flexible-impeller design in the F8B-905 pump family — a bronze-bodied, flange-mounted pump with slotted shaft-end drive. 24699792 is the current OEM replacement for earlier pump \u003cstrong\u003e838522\u003c\/strong\u003e in the applicable Volvo Penta engine cooling-system diagrams.\u003c\/p\u003e\n\u003cp\u003eIf only the flexible impeller is worn and the pump body, shaft, bearings, and seals remain in good condition, an impeller or pump service kit may be sufficient instead of replacing the complete assembly.

Inspect the housing bore for scoring and the shaft for play before deciding. If the pump is leaking at the shaft seal, or the housing bore is worn and no longer retains a good impeller fit, replace the full assembly.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: How often should I replace the seawater pump impeller?\u003c\/strong\u003e\u003cbr\u003e\nA: Annually or per the Volvo Penta service schedule for your specific engine model. Impellers can fail suddenly if run dry even briefly, so regular proactive replacement is better practice than waiting for a cooling failure.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Is the Johnson Pump 10-24130 series a direct substitute for this pump?\u003c\/strong\u003e\u003cbr\u003e\nA: The Johnson Pump 10-24130 series is the equivalent F8B-905 pump family referenced in the application data for these engines. Confirm compatibility by engine model and the Volvo Penta cooling-system diagram before substituting a non-OEM pump assembly.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What causes repeated impeller failures on these engines?\u003c\/strong\u003e\u003cbr\u003e\nA: The most common causes are running the engine briefly without seawater flow (dry-starting), a partially blocked intake or strainer starving the pump, worn pump housing bore that no longer supports the impeller correctly, or an impeller that was installed without lubrication. Check the intake strainer and seacock condition whenever an impeller fails prematurely.\u003c\/p\u003e\n\n\u003chr\u003e\n\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\n\u003cp\u003eThe key selling point for 24699792 is the supersession chain — if a customer has an engine showing \u003cstrong\u003e838522\u003c\/strong\u003e in the diagram or on the old pump, \u003cstrong\u003e24699792 is the current OEM answer\u003c\/strong\u003e and a straightforward order. The most common situation beyond that is customers trying to decide between impeller-only and full pump replacement: if the pump is out and there’s any shaft play, a leaking seal, or visible housing bore wear, the full pump is the right recommendation at this service stage. Intake strainer condition is worth asking about on any seawater pump order — a blocked or collapsed strainer is the number-one cause of premature impeller failure on these engines, and a customer who replaces the pump without clearing a strainer restriction will be back for another pump.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43971688857636,"sku":"24699792","price":1847.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/images_a91cd4d7-2606-495d-975c-091f98af30b9.jpg?v=1789416222","url":"https:\/\/marisolmarine.com\/products\/volvo-penta-seawater-pump-24699792","provider":"Marisol Marine Company","version":"1.0","type":"link"}
