It is engineered for select 5.7L Indmar LTR, LT2, and LT5 engines, including 250, 285, and 285R11 applications, where it circulates raw water to keep the engine running at proper operating temperature.\u003c\/p\u003e\u003cp\u003eThe pump mounts directly to the crankshaft pulley and uses a full 1\/1 cam design with a lip seal to maintain consistent impeller compression and a reliable seal against water intrusion. It draws water through a 1-1\/4 inch hose port. Because this is a self-priming, high-speed pump, it requires a stamped steel crankshaft pulley; it will not operate correctly if paired with a cast pulley, so confirm your pulley type before installing. The housing and internal components are built with marine-grade materials to hold up to continuous raw water exposure.\u003c\/p\u003e\u003cp\u003eFor maintenance, the pump uses the MC97 impeller kit 09-812BT-1 and service kit 09-45825, so replacement parts are readily available when it comes time to service the impeller or reseal the housing. This pump directly replaces the earlier Johnson Pump 10-24930-01, 10-24915-01, 10-24805-01, and 10-24232-1 part numbers, as well as Jabsco EU 22740-0000, making it a straightforward upgrade or replacement for boats already running one of those pumps.\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 10-24946-01\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePump Type:\u003c\/strong\u003e Flexible impeller cooling pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Crankshaft pulley mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCam Design:\u003c\/strong\u003e Full 1\/1 cam with lip seal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePort Size:\u003c\/strong\u003e 1-1\/4 inch hose port\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrankshaft Pulley Requirement:\u003c\/strong\u003e Stamped steel pulley required; not compatible with a cast pulley\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImpeller Kit:\u003c\/strong\u003e MC97 impeller kit 09-812BT-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eService Kit:\u003c\/strong\u003e 09-45825\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 8 inches L x 6.5 inches W x 4.25 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 4.38125 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e5.7L Indmar LTR\u003c\/li\u003e\n\u003cli\u003e5.7L Indmar LT2\u003c\/li\u003e\n\u003cli\u003e5.7L Indmar LT5\u003c\/li\u003e\n\u003cli\u003e250, 285, and 285R11 applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eIndmar 68-5001\u003c\/li\u003e\n\u003cli\u003eIndmar 685001-2\u003c\/li\u003e\n\u003cli\u003eIndmar 685001-4\u003c\/li\u003e\n\u003cli\u003eJohnson Pump 10-24930-01\u003c\/li\u003e\n\u003cli\u003eJohnson Pump 10-24915-01\u003c\/li\u003e\n\u003cli\u003eJohnson Pump 10-24805-01\u003c\/li\u003e\n\u003cli\u003eJohnson Pump 10-24232-1\u003c\/li\u003e\n\u003cli\u003eJabsco EU 22740-0000\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Johnson Pump 10-24946-01 fit?\u003c\/strong\u003e The Johnson Pump 10-24946-01 F6B-9 is built for select 5.7L Indmar LTR, LT2, and LT5 engines, including 250, 285, and 285R11 applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the F6B-9 pump a genuine OEM replacement for Indmar 68-5001?\u003c\/strong\u003e Yes, the Johnson Pump 10-24946-01 is designed as a direct OEM replacement for Indmar 68-5001, 685001-2, and 685001-4.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this pump require a specific type of crankshaft pulley?\u003c\/strong\u003e A stamped steel crankshaft pulley is required for the 10-24946-01.
