Economical

Low owning and operating costs with competitive pricing, longlife construction, and extended service intervals

Easy to install

Plug and play remote instrument panels

Environmentally responsible

Low emission, noise, and vibration levels; 60 Hz meets EPA Tier 2, 50 Hz meets EU 97/68EC Stage II regulations

Safe

Automatic shutdowns for overspeed, high fresh water temperature, low engine oil pressure, and high exhaust temperature (when fitted with a wet exhaust system).

Flexible

Available as an open set or with sound attenuated enclosure, and with radiator-, heat exchanger-, or keel-cooled options

Excellent power quality

Suitable for sophisticated on-board equipment (computers, etc.)

Single source of supply for propulsion and generator sets
