With the launch of its 150 and 175 horsepower 4-stroke outboards in 2006, Suzuki Marine proved once again that bigger isn’t only better – it’s lighter, stronger and faster, as well.

This proof comes in the form of a big-block in-line four cylinder design with the largest displacement (2867cc) of any 4-stroke, four-cylinder motor in this horsepower class, for low-end torque that powers heavy loads out of the hole and acceleration that keeps pulling right through wide-open throttle.

While this sort of performance won’t surprise boaters who have driven Suzuki 4-stroke outboards, they might be surprised that these big-block 4-strokes are lighter than any competitive 4-stroke. In fact, at 215 Kg (465 pounds), these high-tech motors weigh about the same as Suzuki’s previous 2-stroke 150-horsepower outboards.
