Quicksilver's long block assemblies are all-new (not rebuilt, remanufactured, or reconditioned) marine engines and feature 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 long block engine is a new iron block cast to Quicksilver's specifications and designed expressly for marine duty. Thicker castings ensure quieter operation and better durability in saltwater when compared to a standard automotive block. They feature Black-X composite valves that contribute to a 42 percent reduction in valve wear compared to traditional stainless steel valves with hardened seats, while smooth-flowing cylinder heads deliver added performance. Quicksilver Value Series long blocks are cost-effective solutions when replacing an engine with a reliable fuel system and dress components that can be reused, typically when the original engine block has suffered freeze damage. Select the long block needed for your build.

Quicksilver partially dressed crate engines are value-packed alternatives to purchasing a complete new engine if the engine to be repaired has internal damage, but the dress components are in good condition. They are major assemblies that include a new (not rebuilt, remanufactured or reconditioned) long block, as well as the fuel delivery and ignition components required for a high-quality major repair. The partial engine assembly is completed by reusing many components from the engine being repaired, or those components must be purchased separately. The foundation of every Quicksilver crate engine is a new iron block cast to Quicksilver's specifications and designed expressly for marine duty. Thicker castings ensure quieter operation and better durability in saltwater when compared to a standard automotive block. They feature Black-X composite valves that contribute to a 42 percent reduction in valve wear compared to traditional stainless steel valves with hardened seats, and smooth-flowing cylinder heads that deliver added performance. Some crate engines feature modern Multi-Port Fuel Injection (MPI) offering easier starts, improved fuel economy, and snappier throttle response. Quicksilver crate engines are universal power upgrades for Mercury MerCruiser sterndrive and inboard applications, and they're adaptable to other brands of sterndrives and inboards regardless of make. Select the engine desired for your build.
