This year marks a beginning and an end for Caterpillar. For the first time in almost three decades, there will be no 3208 in the Cat marine lineup. Introduced in 1969 as the 210-hp 3160, this 636-cubic-inch V-8 was renamed the 3208 in 1974 and evolved into a 260-hp model–a powerhouse for its time–and finally a 425-hp version. Arguably the engine that started a midrange high-performance marine diesel revolution, the 3208 was the victim of its size and weight yet revered for its bulletproof durability. Caterpillar sold more than 45,000 marine 3208s in the engine’s 32-year run.

At the other end chronologically speaking is Cat’s new 3000 Series marine engines, basically repackaged models from Perkins, which the company bought three years ago. There are three versions: the 3034, a 3.0-liter in-line four; the 3054, also an in-line four but displacing 4.2 liters; and the 3056, available as a 4.0-liter in-line four or a 6.0-liter in-line six, the latter with ratings from 125 to 205 hp. Weighing 1,342 pounds without marine gear, the top-rated version has a weight-to-horsepower ratio of 6.6:1. (309) 578-6298. Fax: (309) 578-2559. www.cat.com.
