    Cummins MerCruiser has three new engines for 2004: the 2.8 ES 200, the QSB5.9-380, and the 1.7 MI 12D.

    The QSB5.9-380’s roots go back to the Cummins 6BTA5.9, and it is the first in the company’s new fully electronic, low-emissions Quantam engine series. A 5.9-liter diesel, it produces 380 hp at 3000 rpm. Noteworthy is its high-pressure common-rail fuel system, which is said to enhance economy, improve the power-to-weight ratio, offer cleaner starting, help eliminate smoke and odor, and reduce noise. Vertically mounted fuel injectors are said to make for more efficient combustion and better durability. The engine also includes a new cylinder head with four valves per cylinder, allowing the engine to breathe better, which translates to increased acceleration and torque.

    The 2.8 ES 200 is a direct-injection, in-line four offering 200 hp and designed to power stern drives. It’s a more powerful version of the company’s 2.8L engine and is also offered in an inboard version, the 2.8 EI 200. A counterbalance has been added to reduce engine vibration, and the company moved the heat exchanger to the side of the engine to reduce its overall size to just 37"x30"x31". A new waste-gated turbocharger is said to provide faster acceleration and reduce smoke.
