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.
