Cummins Inc. introduced a new rating for its QSC8.3 propulsion engine, expanding the keel cooled solution to 600 horsepower with an engine speed of 2800 rpm. This addition to the QSC8.3 power range means Cummins now offers 493 horsepower – 600 horsepower (368-441 kW) for both keel cooled and heat exchanger solutions. Cummins is the first engine manufacturer to bring this power-dense rating with a keel cooling option to the market.
This engine is one of the core power solutions of the more than 1800 vessels that fish in Bristol Bay, Alaska. The QSC8.3 600 horsepower closed-loop, dual circuit, keel cooled rating is an ideal match for vessels needing extra power and speed in the shallow fisheries like those found in Bristol Bay. This is possible thanks to the QSC having the best power-to-weight ratio for its horsepower within Cummins’ offerings coming in at just 1875 lbs (850kg).
The innovative use of a closed-loop keel cooled system to manage engine temperatures eliminates sea water pump issues while offering a zero-discharge solution.
This new QSC8.3 keel cooled rating is now available with a base warranty of 24 months or 1,000 hours.
