Replace a worn or damaged outboard gearcase with an all-new Quicksilver® gearcase, available for many Mercury® and Mariner® outboards between 40 and 300hp. A Quicksilver gearcase is brand new, assembled by factory technicians using the original fixtures and genuine OEM parts for precision that simply can’t be matched by a service shop rebuild. It’s the fastest way to get back on the water, with the confidence that comes with a Quicksilver warranty.
All Quicksilver gearcases are backed by a one-year limited warranty for boats used for recreational purposes.
Built-In Corrosion Resistance
Superior corrosion resistance begins with our proprietary XK360 low-copper alloy. Protection is further enhanced by our Tri-Paint System, which creates a tough, durable corrosion-resistant barrier. Ultra-pure anodes protect the gearcase from galvanic corrosion.
A Quicksilver gearcase is assembled using the same quality gears, shafts and bearings found in a new Mercury outboard, and all rotating parts are aligned and shimmed to tolerances that are hard to match outside the factory environment. Count on many seasons of reliable service from a Quicksilver gearcase.
You'll never catch us cutting corners. Every Quicksilver outboard gearcase comes complete with a durable water pump assembly and is filled with premium Quicksilver High Performance Gear Lube.
