As the original equipment manufacturer, Mercury has the benefit of engineering resources and the experience to remanufacture a true marine-based engine. Every Pro-Series longblock is completely remanufactured with components suitable for marine applications. In fact, the valves, pistons and oil pump are all completely replaced with new pieces that have heavy-duty specifications that exceed those found in most new marine engines. So the specified components of a Quicksilver Remanufacturing longblock are better than a new marine longblock – that’s value! They are precision machined and assembled by the best technicians in the marine industry.

Factory-certified to exceed original performance specifications, longblocks from Quicksilver Remanufacturing come with a one-year factory-backed limited warranty. Major Assembly Protection from Mercury Product Protection is also available to provide up to two years of additional coverage.
