Helmsman Trawlers is one of the first US yacht brands to use the HYUNDAI SEASALL S-Series engines. And WOW — this is an impressive engine!
This 3.0 liter V6 common-rail diesel engine was designed specifically for marine applications, and has a proven track record of reliable operation and low maintenance costs in Europe and Asia. Having recently earned US EPA Tier 3 emissions certification this beautifully-engineered engine is now available in the US.
We are impressed with its smooth, quiet operation. Especially notable is the nearly vibration-free operation at low RPM — compare this to any of the four-cylinder diesels in this horsepower or displacement range, which make a boat feel like life-sized electric football.
And we’re also wowed by its many design features including a readily-accessible raw water pump, a built-in electric oil change pump, integral water-in-fuel sensor, and comprehensive dashboard instrumentation. This compact package fits beautifully into the Helmsman Trawlers 31 Camano engine room, and because of its V6 configuration it allows for excellent access forward and aft of the engine.
Hyundai brags about the use of Compacted Graphite Iron (CGI) for the cylinder block, stating that it is lighter and quieter than conventional grey cast iron, while demonstrating much higher tensile strength, stiffness and fatigue strength than steel or aluminum. Real-world experience has proven this to to be a very long-lasting block in commercial applications, like in the iconic canal boats of Venice.
Specifically for Helmsman Trawlers Hyundai is providing a special 240 hp continuous duty version of the S270 engine — a perfectly-matched and hardy powerplant.
Dealers and service agents for this engine are rapidly increasing throughout the US under the national distributor Performance Diesel Inc.
