Mercury – Water Separating Fuel Filter Bracket | Fuel System Mount | Cast Aluminum | 89876A3

Overview

Every boater knows the fuel system is only as good as the parts you trust to protect it. When you’re miles from the dock with a following sea behind you, the last thing you want is water or debris creeping into your engine. The Quicksilver 89876A3 Water Separating Fuel Filter Bracket is one of those behind-the-scenes components that keeps you running clean and confident. Mounted off the engine, it helps create a safer, more organized fuel layout the kind that makes you breathe easier when you turn the key or throttle up into open water.

Performance & Practical Benefits

Mounting a water separating filter off the engine offers a long list of practical advantages. First, it keeps the filter cooler and more accessible, allowing it to perform more efficiently while making routine maintenance considerably easier. No cramped hands, no twisting around rigging — just a clear, reachable spot to spin a new filter on.

The cast aluminum bracket is built for marine conditions from the ground up. It’s rigid enough to hold the filter securely under vibration and hull impact, yet light enough not to add unnecessary weight to the rigging area. The corrosion-resistant coating stands up to saltwater, spray, and constant moisture exactly what you want from a component that sits low in the bilge or transom compartment.

The included brass fuel connectors thread smoothly and create a tight, reliable seal, reducing the risk of fuel leaks or air intrusion. When paired with a genuine Quicksilver or Mercury water separating filter, the bracket creates a clean, efficient point of defense against water, rust flakes, dirt, and ethanol-related contaminants.

For any boater who’s ever had an engine stumble from bad fuel, the value of this bracket becomes obvious. It’s a small addition that dramatically improves long-term engine health and reliability.

Why Buy OEM

Fuel delivery is not an area where you want guesswork. Aftermarket brackets often cut corners with thin castings, poor coatings, or low-grade threads that don’t hold up under marine vibration. An OEM Quicksilver bracket is engineered to Mercury’s exact tolerances, giving you the proper fit for their filters and the reliability you expect from factory-grade rigging components. It’s the choice experienced boaters make because it lasts, protects the engine, and integrates cleanly into the fuel system.

FAQ

Q1: Which engines is this bracket compatible with?

It works with most Mercury outboards and MerCruiser sterndrives that use standard canister-style water separating fuel filters.

Q2: Why mount the filter off the engine?

Off-engine mounting allows cooler operation, easier access, and better fuel-flow consistency.

Q3: How do I know if this bracket fits my setup?

If your system uses a Mercury/Quicksilver canister-style separator, part number 89876A3 is designed to fit.

Q4: Can it be used in saltwater?

Yes — the cast aluminum and corrosion-resistant finish are built for harsh marine environments.

Q5: What hardware is included?

It includes brass 11/16-16 thread fuel fittings; mounting hardware is typically reused or sourced from your rigging kit.
