Your boat is big enough to live on, fast enough to leave the little fish rocking in your wake, and reliable enough to go wherever big water beckons. Chances are your boat is powered by Cat 3400 engines. At the top of the line is the Cat 3412E, a 1400 bhp (1044 bkW) 12-cylinder piece of engineered art with mid-range power curves that put the competition to shame. This level of power development gives you awe-inspiring acceleration, high power and torque for maneuvers and challenging seas, and great cruising characteristics in smoother water. The source of this electrifying performance? Caterpillar electronic control, with Caterpillar’s patented HEUI fuel system using hydraulically-actuated, electronically-controlled unit injectors that allow full fuel injection pressure at 40 percent rated engine speed. This improves fuel atomization compared to mechanically controlled engines for a more complete burn, accomplishing the twin tasks of improving performance while reducing emissions levels. The 6-cylinder 3406E isn’t far behind its bigger brother, cranking out 133 bhp (100 bkW) per cylinder with the help of electronic fuel injection and a high-position camshaft. Full power and torque are available at 1600 rpm, so you can head out with full confidence in conditions that would cause many engines to bog down. For over 26 years, Cat 3400s have proven their reliability and durability. Now, with a big boost of high performance, they’re also faster…and more fun. Available with optional factory custom paint.
