Johnson Pump 09-812BT-1 MC97 Impeller Kit for F6B-9 Engine Cooling Pump

The Johnson Pump 09-812BT-1 is the MC97 impeller kit specified for use in the Johnson Pump F6B-9 engine cooling pump. This F6B-9 pump is a crankshaft pulley mounted raw water pump used on select 5.7L Indmar LTR, LT2, and LT5 engines, including 250, 285, and 285R11 applications, and the 09-812BT-1 kit supplies the correct impeller and cam components for servicing that pump. Ordering the kit that matches the pump's specified cam type helps ensure the impeller seats and cycles correctly against the F6B-9 pump's housing, supporting proper raw water flow for engine cooling. Because this kit is called out by part number as the impeller kit for the F6B-9 pump, it is the correct choice when rebuilding or servicing that pump rather than substituting a generic impeller. Keeping a kit like this on hand is useful for scheduled impeller replacement, since impellers are wear items that should be changed on a regular service interval to avoid overheating from reduced water flow. The kit is identified by UPC 7330717016586.
