Regular servicing is critical to the health of any outboard engine, especially at the 300-hour mark when deeper system checks and part replacements are required. The 300 Hours Service Kit – 15-20HP EFI 4 Stroke takes the hassle out of maintenance by packaging all essential parts into one convenient kit. It includes a water pump impeller and housing, oil filter, fuel filter, spark plugs, thermostat, gear lube drain gaskets, and a complete set of seals and o-rings — all manufactured to Mercury’s precise OEM specifications.
At the core of this kit is the water pump impeller, a vital component that ensures consistent water circulation through your engine’s cooling system.

The included thermostat regulates engine temperature to support reliable performance and efficient fuel burn.
Clean fuel and oil are just as important. That’s why this service kit comes with premium Mercury oil and fuel filters, designed to remove debris and contaminants that can impair engine performance. Regular filter changes help preserve internal engine components and improve combustion efficiency. Spark plugs included in the kit deliver reliable ignition and smooth starts every time.
To complete the service, high-quality gaskets and seals are provided to ensure all components are leak-free and well protected against the corrosion and wear common in harsh marine environments. Using genuine OEM parts helps protect your warranty and guarantees compatibility and longevity.
