Specifically engineered for the 100-hour service interval, this kit includes all the essential factory-approved parts you need to keep your engine running strong, efficient, and reliable out on the water.

Whether you’re an avid fisherman, water sports enthusiast, or commercial operator, maintaining your high-horsepower Mercury outboard is vital to ensure optimal performance. This all-in-one service kit takes the guesswork out of maintenance by bundling everything you need for the 100-hour service into a single, convenient package.

Inside the kit, you’ll find genuine Mercury components such as a fuel filter, oil filter, water pump impeller, gear lube drain seals, spark plugs, and related gaskets and o-rings. Every item is built to exact Mercury specifications, ensuring a precise fit and long-lasting reliability, even under demanding marine conditions.

The water pump impeller is a vital part of the cooling system, maintaining proper engine temperature by ensuring continuous water flow. Over time, impellers wear down or become brittle, risking reduced cooling and potential overheating. Replacing it at 100-hour intervals is essential to prevent breakdowns and preserve engine health.

Also included is a high-efficiency oil filter that removes harmful particulates, keeping your engine’s internal components clean and properly lubricated. The fuel filter helps maintain smooth operation by preventing debris and water contamination from reaching your engine’s fuel system. Combined with fresh spark plugs, these components help deliver clean combustion, reliable starts, and consistent throttle response.

Whether you perform your own maintenance or rely on a technician, using this OEM service kit ensures your Mercury engine receives parts designed for maximum compatibility, durability, and performance. No more hunting for individual items or worrying about compatibility—everything is packaged and ready for use.

By performing your 100-hour service with this kit, you’re investing in the longevity of your engine, preserving fuel efficiency, and reducing the risk of costly issues in the future. It’s an ideal solution for boat owners who demand reliability and factory-backed performance.
