Steyr says its newest model, the MO174V40 (Steyr 174 Marine Turbo Diesel, for short), is the lightest engine in its class. This in-line four is rated at 165 hp at 4000 rpm, features a maximum torque of 300 at 1800 rpm, and weighs just over 560 pounds (roughly 644 pounds with the optional marine gear). Also new is the MO266K43 (Steyr 266 High Power for short), a four-stroke, in-line six that achieves 260 hp at 4300 rpm and weighs approximately 708 pounds (800 pounds, with optional marine gear).

Both engines feature the new Naval Control Center “Sportline,” an integrated display unit showing the functions of digital instruments, switchboard, fuel management and range calculation, GPS position, and more. Both engines meet all EPA Tier II emissions regulations and feature a dual-stage fuel-injection technology for smoother and quieter operation.
