Tailored specifically for these compact and efficient engines, this kit includes everything needed to perform a thorough and effective service—ensuring smooth, dependable performance out on the water.

Routine servicing every 100 hours is critical to maintaining your engine’s fuel efficiency, reliability, and long-term durability. This kit makes the job simple by combining all factory-approved components in one convenient package. It includes an oil filter, fuel filter, drain plug gasket, spark plugs, and a water pump impeller with associated gaskets and seals—all built to Mercury’s exact specifications for proper fit and lasting quality.

The water pump impeller is a central part of this kit. It’s responsible for circulating water through the engine to regulate temperature. Replacing it regularly helps prevent overheating, which can cause serious internal damage. The included gaskets and housing seals ensure leak-free operation and consistent cooling system performance.

Clean filters are essential to the health of your engine. The oil filter traps impurities that accumulate during normal operation, while the fuel filter protects against debris that can reduce fuel efficiency and engine response. Replacing both at 100-hour intervals keeps your engine running clean and strong. The high-quality spark plugs ensure reliable ignition, smooth running, and easier cold starts.
