There’s a certain comfort that comes from knowing your engine is getting clean, reliable fuel every single time you turn the key.

Performance & Practical Benefits

A clean, efficient fuel filter is something you feel right away, even if you never actually see the part. With the 8M0046751 installed, your throttle response becomes smoother, idling steadier, and your overall engine feel more predictable. It’s the kind of difference you notice most during long weekends when the boat runs hour after hour without a hiccup.

This filter is designed specifically for the demands of MerCruiser sterndrives. The canister captures moisture, debris, and tiny contaminants before they ever reach injectors or carburetor passages. That means fewer performance drops, fewer hard-start moments, and far less long-term wear.

Installation is simple and forgiving—no strange threads, no questionable seals, no guesswork. Everything you need comes in the box: the filter, the gaskets, the O-rings. They seat firmly and cleanly, giving you a tight, secure fit that won’t leak or rattle loose.

Durability is another big win. Mercury designed this filter to handle real marine conditions—heat, humidity, vibration, and long idle periods. It keeps doing its job quietly in the background so you can spend more of your time enjoying the water instead of wrenching on the dock.

Why Buy OEM

Boaters who’ve spent enough seasons maintaining their own rigs know the truth: fuel filtration is not a place to cut corners. Aftermarket filters can fit “close enough,” but close isn’t good enough for a high-demand marine engine.

With a genuine Mercury OEM part, you’re getting:

• A perfect seal every time
• Filtration built to the engine’s exact pressure and flow demands
• Longer service intervals
• Better protection from moisture and debris
• Fitment designed for MerCruiser fuel pump housings specifically

It’s the kind of purchase that pays for itself in fewer repairs, smoother performance, and more reliable days on the water.
