Performance & Practical Benefits

Changing the oil on a marine engine isn’t just a chore—it’s the most important thing you can do to keep that engine running smoothly. With this kit, you get Mercury’s trusted 25W-40 marine oil formulated to handle long periods of high load, extended idle times, and the constant heat cycling that happens on the water. It hangs onto its viscosity, resists foaming, and has corrosion inhibitors built for the marine environment.

Once you complete the oil change, you’ll likely notice the difference right away. The engine settles into a steadier idle, throttle transitions feel a little sharper, and everything sounds more confident under load. The filter included in the kit is built for the specific demands of a boat engine—steady pounding, constant movement, and high internal temperatures. It’s all designed to protect your investment and make your time on the water feel as trouble-free as possible.

Why Buy OEM

When you buy a Mercury Marine part, you’re buying something created for your engine—not a guess, not a “universal fit,” but a part engineered to match the exact needs of your boat. The oil in this kit is formulated for marine use from the ground up, and the filter threads on smoothly with perfect fitment. It’s the safest, most dependable way to service your engine, and it saves you the headaches that cheaper aftermarket parts tend to bring. If you’re going to trust anything on your boat, trust the parts designed by the people who built the engine.
