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 866003A01 Intermediate Exhaust Elbow Kit is a genuine OEM replacement exhaust component designed for MerCruiser MCM V-8 sterndrive engines equipped with 1.7-inch (43 mm) exhaust risers. This kit provides the critical intermediate elbow assembly required in a standard sterndrive application with through-the-propeller exhaust routing.

The intermediate exhaust elbow connects the exhaust riser to the exhaust bellows and tubing, playing a key role in safely routing hot exhaust gases away from the engine and out through the drive. Replacing a worn or corroded elbow with a genuine Quicksilver part ensures a factory-precise fit and maintains the integrity of the entire exhaust system.

Key Features:

  • Genuine Quicksilver OEM factory part — not aftermarket
  • Designed for MerCruiser MCM V-8 sterndrive engines with 1.7 in. (43 mm) risers
  • Intermediate elbow connects exhaust riser to exhaust bellows and exhaust tube
  • Essential for standard sterndrive applications with through-the-propeller exhaust
  • Engineered for factory-level fit, function, and durability
  • Manufacturer Part Number: 866003A01

Periodic inspection and replacement of exhaust elbows is recommended as part of routine MerCruiser engine maintenance. Always disconnect the battery before servicing exhaust components, and torque all hardware and hose clamps to Mercury's specified values during installation.

I'm always had a great experience!

The site does not inspired confidence due to the current look and feel. However the delivery was fast and the issue with ordering was resolved in matter of days. The only down side was that on of the parts did not match the original part of my vehicle. As many other autoparts stores they all provide the same part numbers but still it is not accurate. Other than that it has been a good overall experience.

good so far
