Quicksilver Marine Transmissions, Parts & Accessories

When it comes to keeping a marine sterndrive or inboard drivetrain in peak operating condition, few names carry the weight of Quicksilver. As the parts and accessories arm of Mercury Marine, Quicksilver occupies a unique position in the marine industry: its components are considered factory original equipment for Mercury and MerCruiser engines, yet they are available through a much wider network of retailers than Mercury-branded parts alone.

Marine transmissions, parts, and accessories represent one of the most mechanically demanding segments of any boat's drivetrain. The transmission — sometimes called a marine gear or drive unit — must transfer engine power to the propeller while enduring constant exposure to water, salt, vibration, and wide temperature swings. Getting these components right is not optional; it is the difference between a reliable day on the water and an expensive tow back to the dock.

Factory-Tested, Ready to Install

Quicksilver marine transmissions are fluid-filled, factory-tested, and ready to install — and each unit includes a package of required mounting and rigging components, so there is no need to source extra parts to complete the installation, saving both time and money. This turnkey approach reflects Quicksilver's philosophy of making professional-grade service accessible to boat owners and independent technicians alike.

Quicksilver parts are manufactured by Mercury Marine and come from the parts and accessories (P&A) side of the company. Where there is a choice between Mercury and Quicksilver packaging, Quicksilver parts are 100% the same as the equivalent Mercury part. That means when you install a Quicksilver transmission component, you are installing the same engineering that goes into a brand-new Mercury-powered vessel.

Rigorous Testing Behind Every Component

No aftermarket company comes close to the level of research and design found in Quicksilver products, and no other company tests their products like Quicksilver — with millions of hours spent on fired-engine testing and analysis. For transmission-related parts — components that operate under high torque loads and continuous stress — this level of validation matters enormously. Seals, gaskets, bearing carriers, and gear lube drain hardware all benefit from the same engineering discipline applied to Quicksilver's full product line.

Broad Compatibility Across Major Marine Brands

For maintenance or repair, Quicksilver offers a wide selection of OEM-quality parts for many of the most popular brands on the water, including Mercury®, Mariner®, Honda®, Yamaha®, Evinrude®/Johnson®, Suzuki®, and more — and these parts fit and function as well as the original components. This broad compatibility makes Quicksilver transmission parts and accessories a practical choice whether you are servicing a classic MerCruiser sterndrive or a multi-brand fleet.

Quicksilver products are available in retail stores, independent marine dealerships, powersports dealerships, and local convenience stores — virtually everywhere marine and powersports parts are found — and Quicksilver offers 40,000+ parts across 12 product lines worldwide. Within the transmissions, parts, and accessories category specifically, that breadth translates to a dependable supply of the exact components needed for gear-lube services, seal replacements, and full transmission rebuilds or swaps.

The Right Choice for Sterndrive & Inboard Drivetrain Service

Whether you are replacing a worn seal, refreshing gear lubricant, or installing a complete replacement transmission on a MerCruiser-powered cruiser, Quicksilver's transmissions, parts, and accessories deliver the confidence that comes from genuine OEM engineering.
