A vessel that needs 16 to 20 kW is large enough that continuous power is critical to its operation. Unfortunately, most sets in this range have small displacement, light duty diesels that can’t stand up to heavy use. Some even need turbochargers to compensate for their small displacement.
The M844W3 is different. Powered by a naturally aspirated four cylinder diesel, this set has the low end torque needed to start large electric motors. Amazingly, however, it weighs under 900 pounds and is compact in size. The M844W3 meets US EPA Tier III emission standards protecting the environment we all enjoy.
Vibration isolation mounts, cast air intake manifold and sound maze intake silencer make the set remarkably smooth and quiet. A sound enclosure is available to increase the quietness of the generator.
Operation and maintaince are simple. A 20 foot wire harness and control panel lets you run the set from your boat’s bridge. The engine’s DC electrical system uses reliable relays instead of delicate printed circuit boards. If a failure should occur, you can simply plug in an inexpensive relay. All service points are on one side within easy reach, and the sea water pump’s location makes impeller changes a snap.
Need hydraulic power? Add an optional front PTO (power take off) with an electric clutch. With this option, the touch of a button gives you power for your bowthruster and winches without starting your main engine.
