Quicksilver® offers complete all-new, drop-in replacement engines for many boats originally powered by legendary Mercury® MerCruiser® sterndrive and inboard engines, many Volvo Penta® sterndrives, and any brand of gasoline inboard engine, often with a significant upgrade in durability, performance and technology. Quicksilver offers a replacement gasoline engine for almost any type of boat, from a compact runabout to a classic inboard tow boat to a long-range cruiser. When you choose a Quicksilver complete engine, you’re choosing performance, protection and peace of mind.
All-New Marine Engines
These are genuine marine engines, fitted with U.S. Coast Guard-approved components and corrosion-resistant fasteners, and finished with a durable corrosion-resistant paint process. You get a brand-new engine – never rebuilt or remanufactured – with improved components, technology and built-in durability designed to withstand years of marine duty – one of the most abusive and demanding environments for any engine.
The foundation of every Quicksilver complete engine is a new iron block cast to our specifications and designed expressly for marine duty. Thicker castings ensure quieter operation and better durability in saltwater when compared to a standard automotive block.
Black‑X composite valves contribute to a 42% reduction in valve wear compared to traditional stainless steel valves with hardened seats, for longer engine life, especially in the presence of modern ethanol-blended fuels. Smooth-flowing Quicksilver cylinder heads deliver added performance in sterndrive or inboard installations.
Multi-Port Fuel Injection (MPI)
The modern Multi-Port Fuel Injection (MPI) featured on all Quicksilver V8 complete engines offers easier starts, improved fuel economy and snappier throttle response when replacing an older engine with a carburetor or early fuel-injection system.
Three-Year Limited Warranty
Quicksilver engines are infused with quality. We’re so confident in them that we back every engine with a three-year limited warranty, the strongest in the industry.
Protected by Engine Guardian
To protect your investment, most Quicksilver complete engines feature a helm-mounted Audio Warning System with Engine Guardian to protect against engine damage. Engine Guardian monitors the critical sensors on the engine and will respond to a problem by emitting a warning tone and/or reducing power to protect the engine.
Easy Repower Rigging
Quicksilver complete marine engines are designed to work with analog (cable) controls, which helps keep the repower project easy and affordable. Display engine information on your choice of analog or SmartCraft® digitally driven gauges and displays (sold separately).
