Built for engines from the year 2000 onwards, this 300-hour service kit includes all the essential parts required to keep your engine running efficiently, reliably, and with optimal performance after extended use.

Whether you’re powering a family runabout, fishing vessel, or light commercial boat, the 3.0L engine is a dependable workhorse—and regular servicing is the key to preserving its performance and longevity. This 300-hour kit brings together all the critical components needed to perform scheduled maintenance in one convenient package, helping you avoid costly breakdowns, preserve fuel efficiency, and maximise your time on the water.

Inside this kit, you’ll find a complete set of genuine OEM Mercury parts, including oil filter, fuel filter, spark plugs, water pump impeller, gaskets, seals, o-rings, and other key service items specific to 3.0L carburettor RWC models. Every component is precision-engineered to Mercury’s specifications, ensuring an exact fit and reliable operation under demanding marine conditions.

One of the most important elements of this service kit is the raw water pump impeller, which should be replaced regularly to maintain proper engine cooling.

The included spark plugs and filters ensure smooth ignition and clean fuel delivery, while seals and gaskets prevent leaks and maintain system integrity.

Servicing your engine at the 300-hour mark is vital to keeping it running strong, especially in saltwater or high-load conditions. This kit supports the full scope of routine maintenance recommended by Mercury, giving peace of mind to boaters who demand dependability and performance season after season.

If you’re performing your own maintenance or handing it off to a marine technician, the 3.0L Carburettor RWC (2000 and newer) SERV KIT-300 HRS simplifies the process, ensuring you have everything you need in one reliable, quality-assured kit.
