Mercury – Quicksilver Engine Block Mount Oil Filter | Filtration System | Marine-Grade Construction | 883702Q

Overview

There’s a real sense of comfort that washes over you when your MerCruiser settles into a smooth idle — that steady, confident hum telling you the engine is being protected the way it should. Clean oil is the lifeblood of any stern drive, and when it’s filtered properly, everything runs easier. Starts feel gentler, the throttle responds the way you expect, and you can relax knowing the heart of your boat is well cared for.

That’s exactly what this Mercury Marine part delivers. It’s one of those components you rarely think about, but you absolutely feel the difference when it’s doing its job right.

Performance & Practical Benefits

This oil filter plays a bigger role than many boaters realize. Every time you turn the key, the anti-drain back valve ensures immediate lubrication — no dry spins, no hesitation, no harsh engine chatter. Out on the water, that translates to smoother throttle transitions, more consistent oil pressure, and a quieter, steadier running engine.

The M-Pleated filtration media captures a wide range of contaminants without restricting oil flow. That means the engine continues to run clean and cool even during long cruising days, towing water toys, or pushing through choppy conditions. And the thicker metal shell does more than just feel sturdy — it protects the filter body from corrosion, impacts, and vibration, giving you long-lasting confidence in rough water or salt-heavy environments.

Installation is simple. Thread it on, snug it down with an oil filter wrench, and you’ll feel that secure, confident fit that tells you the job is done right. It’s the kind of maintenance task that takes only minutes but delivers protection that lasts all season.

Why Buy OEM

Engine protection isn’t the place to gamble. With part number 883702Q, you’re getting a Mercury Marine part built to the exact specifications of MerCruiser V6 engines. Everything — from the internal media to the valve design and metal thickness — is engineered around the needs of these motors.

Aftermarket filters often look similar, but they rarely match the filtration quality, anti-drain back reliability, or corrosion resistance found in an OEM part. A genuine filter protects your investment, extends engine life, and helps ensure your boat performs the way it was designed to.

If a fellow boater asked which oil filter to trust, this is the one I’d recommend without thinking twice.
