Big displacement, combined with the lightest weight and smallest package size means strong, long-lasting performance on light and heavy hulls alike. The 150 maximizes your time on the water by making basic maintenance easy to do and quick to perform by you.

So they need 3 liters of displacement to get 150 HP because there is only 2 valves per cylinder. 4 valves per cylinder is more efficient and uses less fuel with less displacement. I'd like to see fuel economy numbers vs a Yamaha.

Evinrudes are pure, unadultered crap. I had a brand new 150, and went through three powerheads in the first two seasons. I sold that piece of crap.
