Quicksilver Engines & Components

Quicksilver Oil Filters

Quicksilver oil filters are premium, marine-grade filtration components engineered specifically for outboards, inboards, and sterndrive engines, such as Mercury, MerCruiser, and Mariner. Manufactured to meet original equipment manufacturer specifications, they protect marine engines from damaging contaminants and prevent dry starts. Key features and benefits: * Marine-grade durability: The housings are typically built with metal shells that are 50 percent thicker than standard automotive filters and feature a corrosion-resistant finish to survive harsh aquatic environments * Anti-drain back valve: Designed to ensure immediate start-up lubrication and eliminate engine-damaging dry starts * Superior filtration: Uses specialized M-pleated synthetic/micro-glass media that screens particles smaller than 1/1000th of an inch, capturing dirt without sacrificing oil flow * Broad compatibility: While primarily for Mercury and MerCruiser motors, Quicksilver also makes exact-fit replacement filters for other major outboard brands like Yamaha, Honda, and Nissan/Tohatsu * Canister style filters are available in a wide range of sizes and threads

Quicksilver Long Block Assemblies

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.
