Caterpillar. The very definition of the diesel advantage.

Gas engines are fine for smaller boats that don’t get too far from shore. But if you’re serious about offshore fishing or long distance cruising in boats over 30 ft. (9.1 m), you want diesel engines. They offer a number of advantages over gas, including greater durability, power, efficiency, resale value and safer fuel.

Caterpillar sells more marine diesel engines over 200 bhp (150 bkW) than any other manufacturer in the world. We think the reason for this is that since 1935 we have invested heavily in research and development to improve upon the natural advantages of diesel power. New engines are continuously being developed. Existing models are improved and updated to take advantage of new materials, new technologies like electronic control and new information accumulated from real-world operating experience. So when the International Maritime Organization IMO announced new marine engine emissions regulations for the year 2000, Caterpillar had the knowledge and experience to quickly make their engines IMO compliant while minimizing potential performance impacts.

Choosing Caterpillar means choosing from seven engine families with power ratings from 210 to 9655 bhp (157 to 7200 bkW). Weight-to-power ratios as low as 3.78 lbs./hp. Seven high-performance models featuring state-of-the-art electronic control. A five year warranty for non-revenue producing boats. Ultimately, there’s a set of Cat® marine diesel engines designed to help you achieve secure excitement. And all meet IMO NOx emissions standards.
