S270 High Speed Diesel – Hyundai SeasALL (California)
For California boaters who want strong acceleration, quiet cruising, and dependable long-run performance, the Hyundai SeasALL S270 High Speed Diesel delivers a powerful blend of modern diesel technology and compact, efficient packaging. Built around a 3.0L V6 CRDi platform, the S270 produces 270 PS (199 kW) with high torque for confident planing, steady midrange pull, and controlled handling in coastal chop.
Available across multiple propulsion configurations—Sterndrive (S270s), Shaftdrive (S270P), and Waterjet (S270J)—the S270 is designed to fit a wide range of California applications, from coastal cruisers to fast day boats.
Power, Torque, and Modern Diesel Response
At the heart of the S270 is a 4-stroke, 24-valve DOHC diesel featuring E-VGT (electronically controlled variable geometry turbocharging) with an intercooler and fresh water cooling. The result is strong, usable power across the rpm range and the kind of torque delivery that makes docking, maneuvering, and getting on plane feel effortless.
A piezo-controlled common rail direct injection (CRDi) system helps deliver crisp response and efficient fuel use while supporting smooth, quiet operation—ideal for long coastal runs and frequent throttle changes in California’s mixed conditions.
Built for Pleasure Duty Reliability
Rated for Pleasure Duty (S5), the S270 is engineered for dependable performance in real boating use—day trips, weekend cruising, and regular coastal operation. Hyundai’s focus on durability shows up in the engine’s construction and materials, designed to support longevity and confidence over time.
Durable Cylinder Block Technology
Hyundai SeasALL uses Compacted Graphite Iron (CGI) for the cylinder block, a material choice that offers key advantages for marine use. Compared to conventional grey cast iron, CGI is lighter and engineered for greater strength and stiffness, supporting long-term durability and reliability in demanding marine environments.
