Performance & Practical Benefits

A well-maintained engine behaves differently—you can feel it in the throttle response, hear it in the cleaner idle, and trust it when you push through a tight turn or a windy channel. This kit supports that reliability by making sure your filtration system is fresh and efficient.

The oil and fuel filters deliver tight, consistent filtration, keeping debris and contaminants out of critical pathways. Electroplated housings protect against corrosion, so even if you boat in brackish or saltwater, your components stay in top shape. The gearcase drain seals help ensure a secure, leak-free service when refreshing your gear lube.

Everything fits the way it should, making the job straightforward whether you’re a seasoned DIY boater or working with a marine tech. When you finish the service, you’ll feel that steady confidence knowing your engine is ready for another season of reliable power.

They’re engineered to match your exact engine specs, built from materials designed for marine punishment, and tested far beyond typical aftermarket standards. You’ll save frustration, avoid trial-and-error, and protect the investment sitting on your transom. It’s simply the part that fits right the first time—and keeps fitting right for years.
