For some time now the propulsion arm of Alaska Diesel Electric (which sells genset under the Northern Lights brand) has offered a series of large-displacement (7.1- to 23-liter) diesels based on industrial engines from Komatsu. This year it ventures into smaller territory with two four- and three six-cylinder models based on the new John Deere marine engines (see above). In fact, if you compare the stats of these new engines with those offered by Deere, you'll see some remarkable similarities.

All engines are offered in continuous-duty, medium-horsepower, and high-output versions. There are two versions of the 4.5-liter four, a naturally aspirated model maximum rated at 85 hp and a turbocharged (but not aftercooled) version maximum rated at 135 hp. The same basic engine is available in an in-line six displacing 6.8 liters, of which two models are offered: a naturally aspirated motor with a high-output rating of 130 hp and a turbocharged version rated at 174 hp. A third version of this engine is offered only as a high-output engine at 225 hp.

So why not just buy the engines directly from Deere? Lugger says the biggest reason is its large parts and service network and ability to offer a number of custom configurations. Deere has a major presence in commercial craft but is just getting its feet wet in pleasure marine power.
