Helmsman Trawlers 31 Sedan

This Hyundai S240 engine was built by Hyundai as a factory modified version of its S270 engine, and is rated for continuous duty at full throttle (not that you would necessarily want to do that -- but you could!).

The Hyundai V6 diesel engine block is constructed from Compacted Graphite Iron (CGI) which Hyundai reports to be lighter and quieter than conventional grey cast iron, while demonstrating much higher tensile strength, stiffness and fatigue strength than steel or aluminum.

This is really a terrific engine -- not well-known in the US yet, but very popular and well-regarded elsewhere for its quiet, smooth operation, reliable long-life performance even in commercial applications, and design for straightforward servicing.

Whisper Power M-SC 3.5 generator in sound enclosure. Located in lazarette for quiet. Exhaust/water separator further reduces noise while in operation.
