Johnson Pump MC 97 Replacement Impeller Kit f/Sherwood 15000K Impeller Kit

The Johnson Pump MC 97 Replacement Impeller Kit for Sherwood 15000K is the marine maintenance solution serious anglers and boat owners rely on to keep raw-water cooling systems running at peak efficiency. After years on the water, you know that a failing impeller is one of the quickest ways to overheat an engine and cut a day short—or worse, cause catastrophic damage. This replacement kit restores proper coolant circulation when wear or deterioration compromises your original impeller, making it an essential spare for any offshore or extended cruising operation.

Built from marine-grade MC 97 rubber compound, this impeller kit is manufactured to strict tolerances to ensure seamless fit and reliable performance within the Sherwood 15000K pump housing. The engineered rubber blades are designed to displace water efficiently without cavitation or slippage, maintaining consistent flow rates under load and variable operating temperatures. Johnson Pump's engineering is trusted by leading engine manufacturers worldwide, and this replacement assembly delivers the same durability and precision engineering as OEM components—but at a fraction of the cost of complete pump replacement.

Whether you're conducting routine preventive maintenance or responding to overheating issues mid-season, this kit is compatible with Sherwood 15000K pump systems commonly found on inboard and transom-mounted cooling setups. Installation is straightforward for anyone with basic mechanical skill, requiring only impeller removal and housing access—no extensive disassembly needed. Keep a replacement on board during extended trips; at 0.6 lbs and compact dimensions, it fits easily in any engine compartment tool kit and can mean the difference between a completed fishing trip and a costly tow-in.
