Made from MC97 material engineered for cooling applications, the impeller is designed to deliver stable pressure over time, resist swelling, and minimize the fatigue-related failures that shorten the life of lower-quality replacements. Its self-priming capability and correct impeller geometry help ensure proper cooling flow reaches the engine immediately at startup, which is critical for preventing overheating damage during the first seconds of operation.\u003c\/p\u003e\u003cp\u003eThis is a full kit, not just a bare impeller: it includes the impeller itself, an o-ring, a gasket, and 7 grams of impeller lubricant to ease installation and protect the impeller vanes on first run. The 09-808B-1 measures 1.58 inches in outer diameter and 0.75 inches in width, with a 6-spline inner bore. It is a direct replacement for Jabsco No 22405-0001, letting boat owners cross over from that part number without changing pump housings or hardware.\u003c\/p\u003e\u003cp\u003eFitment covers Volvo Penta MB and MD engines, Westerbeke 8-10 kW generator sets, and Onan generators in the 5.0, 5.5, 6.0, 6.5, 7.5, and 9.0 kW range. Always confirm your engine or generator model against these applications before ordering, since impeller kits are not universal across pump families.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Johnson Pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 09-808B-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Contents:\u003c\/strong\u003e Impeller, o-ring, gasket, 7 grams impeller lubricant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e MC97\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter:\u003c\/strong\u003e 1.58 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Diameter:\u003c\/strong\u003e 6 splines\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 7330717008734\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eVolvo Penta - MB, MD engines\u003c\/li\u003e\n\u003cli\u003eWesterbeke - 8-10 kW\u003c\/li\u003e\n\u003cli\u003eOnan - 5.0, 5.5, 6.0, 6.5, 7.5, 9.0 kW\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eJabsco 22405-0001\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Johnson Pump 09-808B-1 kit include?\u003c\/strong\u003e The 09-808B-1 kit includes the impeller itself, an o-ring, a gasket, and 7 grams of impeller lubricant, so everything needed for a single impeller change is in one box.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 09-808B-1 a direct replacement for Jabsco 22405-0001?\u003c\/strong\u003e Yes, the Johnson Pump 09-808B-1 is a direct replacement for Jabsco No 22405-0001.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the 09-808B-1 impeller kit fit?\u003c\/strong\u003e This kit fits Volvo Penta MB and MD engines, Westerbeke 8-10 kW generator sets, and Onan generators rated 5.0, 5.5, 6.0, 6.5, 7.5, and 9.0 kW.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size is the impeller in the 09-808B-1 kit?\u003c\/strong\u003e The impeller has a 1.58 inch outer diameter, a 0.75 inch width, and a 6-spline inner diameter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 09-808B-1 impeller made from?\u003c\/strong\u003e It is made from MC97 material, which is engineered specifically for cooling water applications in marine engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Johnson Pump 09-808B-1 weigh?\u003c\/strong\u003e The 09-808B-1 impeller kit weighs 0.1 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 09-808B-1 kit come with lubricant for installation?\u003c\/strong\u003e Yes, 7 grams of impeller lubricant is included in the 09-808B-1 kit to help protect the impeller vanes during initial startup.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 09-808B-1 impeller run dry?\u003c\/strong\u003e The 09-808B-1 is designed with minimized swelling and fatigue resistance for long service life, but like most rubber impellers it should be run with cooling water present rather than dry.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy does the impeller need to be replaced periodically?\u003c\/strong\u003e Impellers such as the 09-808B-1 wear over time and can develop cracked or worn vanes, which reduces cooling flow; the kit's stable-pressure design and fatigue resistance are intended to extend the interval between replacements.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 09-808B-1 kit include a gasket for the pump housing?\u003c\/strong\u003e Yes, a gasket is included along with the impeller, o-ring, and lubricant in the 09-808B-1 kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Johnson Pump 09-808B-1?\u003c\/strong\u003e The UPC for the Johnson Pump 09-808B-1 impeller kit is 7330717008734.\u003c\/p\u003e","brand":"Johnson Pump","offers":[{"title":"Default Title","offer_id":49028225630427,"sku":"JON-09-808B-1","price":31.17,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/09-808B-1.2__05673.1558352719.500.750.jpg?v=1785164631","url":"https:\/\/www.goodvibesmarina.com\/products\/johnson-pump-09-808b-1-f35-impeller-kit-1-58-inch-replaces-jabsco-22405-0001-volvo-penta-mb-md","provider":"Good Vibes Marina","version":"1.0","type":"link"}
