Quicksilver

<h3>Quicksilver: The Marine Enthusiast&apos;s Trusted OEM Brand</h3><p>For boaters who refuse to compromise on quality, <strong>Quicksilver</strong> has been the benchmark for marine parts, accessories, and engine care products since 1950. Based in Fond du Lac, Wisconsin, Quicksilver operates as the parts and accessories brand of Mercury Marine — and that heritage is central to everything it makes. As the only marine aftermarket brand manufactured and recommended by an original-equipment manufacturer, Quicksilver brings factory-level engineering directly to boat owners, professional technicians, and weekend warriors alike.</p><p>What sets Quicksilver apart from generic aftermarket suppliers is its direct lineage to the engineers who designed the engines in the first place. Every component is engineered, tested, and manufactured with the same exacting standards as the original equipment it replaces. The result is a product line that fits right the first time and delivers the reliability boaters depend on — whether they&apos;re navigating calm inland lakes or pushing through demanding saltwater conditions.</p><p>Quicksilver&apos;s catalog spans more than 40,000 parts across 12 product lines, covering outboard and sterndrive engines from Mercury, Mariner, Yamaha, Honda, Evinrude, Johnson, Suzuki, and more. Among the most critical components in that lineup are Quicksilver Fuel Pumps, which are built to deliver factory fit and consistent fuel delivery across a wide range of outboard applications. Reliable fuel delivery is the foundation of engine performance, and Quicksilver&apos;s fuel system components are engineered to handle the demanding conditions of marine use — including compatibility with current fuel formulations.</p><p>Beyond fuel systems, Quicksilver is a go-to source for Propeller Parts &amp; Accessories that help boaters maintain and optimize their propulsion systems. From hub kits that protect both prop and gearcase to installation hardware and prop tools, these components are designed to the same tolerances as the drives they support. Proper propeller maintenance is one of the most impactful things a boat owner can do for performance, efficiency, and engine longevity — and Quicksilver makes that job straightforward.</p><p>The brand&apos;s commitment extends across lubricants, impellers, thermostats, anodes, fuel filters, oil filters, maintenance kits, and complete service packages — all engineered for the marine environment and tested to meet or exceed the standards of major engine manufacturers. Whether you&apos;re performing routine seasonal maintenance or tackling a more involved repair, Quicksilver provides the parts that restore your engine to peak operating condition.</p><ul style="list-style:disc"><li>OEM-backed engineering from Mercury Marine</li><li>Compatible with Mercury, Yamaha, Honda, Evinrude, Johnson, Suzuki, and Mariner engines</li><li>Over 40,000 parts spanning 12 product lines</li><li>Formulated and tested for freshwater and saltwater environments</li><li>Trusted by DIY boaters and professional marine technicians since 1950</li></ul><p>When reliability on the water is non-negotiable, Quicksilver delivers the peace of mind that only a true OEM-backed brand can provide.</p>

Product Details

The Quicksilver 43713 is an OEM genuine foam gasket seal designed to seal the gimbal housing interface at the transom opening on MerCruiser sterndrive installations. This transom seal is a critical component that prevents water intrusion into the boat's transom cavity, protecting the bilge and structural integrity of the hull.

This seal is the correct OEM replacement for Alpha One Gen II and all Bravo sterndrive systems (1991 and up), making it one of the most widely used transom seals in the MerCruiser product line. It is sold individually.

Key Features:

  • OEM Quicksilver/Mercury Marine part — guaranteed correct fit and material quality
  • Foam gasket construction provides a reliable, compressible seal against the transom plate
  • Designed for use during sterndrive removal, installation, and transom assembly service
  • Replaces worn or compressed seals that may allow water intrusion
  • Direct OEM replacement — no modification required

Cross-Reference Part Numbers:

  • Mercury / Quicksilver OEM: 43713
  • Sierra: 18-2724
  • GLM: 86711
  • Mallory: 9-72420

Replace this seal any time the sterndrive unit is removed from the transom to ensure a proper water-tight fit upon reinstallation. Mercury Marine and Quicksilver products carry a 1-year factory warranty against defects in materials and workmanship.

Excellent deal!!! I was not able to find a better price anywhere. Fast shipping & just what I wanted.

Free shipping and a great price.

The product came at the very last minute. So we had to do something different plus the &quot;return&quot; directions on the website were not clear, i.e. the return process is not easily executed.

Good, lower price.

Shipping took about a week total from start to finish. A little slow as far as I'm concerned but the awesome price definatley made it worth it. Will order from them again 4.9/5

Good

Quick and easy checkout THANKS

Best price you will find and fast shipping ( took only 2 days to receive it after ordered it)

Stuff I was looking for was easy to find and checkout was easy. All parts were for the vehicle i selected and fit perfectly.

I bought a Motive pressure brake bleeder from Autoplicity. I have been looking around for different prices for quite a while, and their price, even with shipping cost, was the lowest. After ordering, I received a notification of shipment and tracking number. The item arrived well packaged, complete, and intact within a few days. I am looking forward to using it.
