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 93322A12 is an OEM 6-inch exhaust riser spacer kit designed for MerCruiser sterndrive and inboard engines. This genuine Mercury Marine kit adds 6 inches (152 mm) of rise to the exhaust manifold assembly, providing critical clearance for proper exhaust system installation and reliable engine operation in marine applications.

Key Features:

  • Genuine OEM Quicksilver/Mercury Marine part — not aftermarket
  • Provides 6-inch (152 mm) of rise to center riser exhaust manifolds
  • Kit includes 6-inch spacer blocks, full-flow riser gaskets, mounting bolts, nuts, and washers
  • Compatible with all MerCruiser center riser manifolds on V6 and V8 engines
  • Designed for MerCruiser V6 carbureted and TBI sterndrive engines with 2-piece exhaust manifolds (serial no. 0M614999 and below)
  • Also fits MerCruiser/MIE/Tow Sports V8 engines (305, 350, 377, 454 & 502 CID) with cast iron elbows (serial no. 0M299999 and below)
  • Fits MerCruiser V8 (305 & 350 CID) carbureted engines (serial no. 0M300000–0M599999)
  • Fits MIE & Tow Sports carbureted engines (serial no. 0M300000–0M316999)

This riser extension kit is the correct OEM solution when additional exhaust manifold height is needed — commonly required during repowering, hull modifications, or when upgrading to a higher-profile exhaust system. Always verify fitment using your engine serial number prior to installation.

A week ago I ordered a H3RHG100C 1.4 lb Halotron fire extinguisher. I mentioned "a week ago" because that is how long it took from order to delivery across the U.S.!! Now that I look at the paperwork, it wasn't even a full week. Autoplicity is now my #1 parts supplier for my 2010 Camaro. They could not have been any better overall. Ordering, checkout, stock and shipping. All above and beyond my expectations Great site, great communication. A1 people.

Great overall buying experience.

Great price and free shipping. Can&quot;t beat that.

So far so good!

Good

Easy to use site, very intuitive.

Shopping was fast and easy. The paint was the cheapest on Google search.

I was a bit skeptical about your website since I've never purchased from you before, but your customer service representative was great at answering my questions. Thanks.

This is the first time I've ordered from this site, but things look good from what I can tell so far. They had the parts I was looking for (including a fairly specialized racing part) for a price slightly lower than other places I had looked, and my order shipped the next business day. At the time I wrote this, they were also offering $5 back on my order for writing a review. ;-)

Great seller, great prices!!

Great customer service. Prompt shipment and excellent prices. I will defiantly be ordering from them again. Just wish I would have found them sooner!!
