Are Four-Strokes More Efficient Than Two-Strokes?

Myth: Four-stroke outboards are more fuel-efficient than two-strokes.

You’ve got to burn fuel to make horsepower. Comparisons are often made between older, carbureted two-strokes and newer fuel-injected four-strokes. In those cases, the enhanced economy comes from the fuel delivery system, not from the number of revolutions in a power cycle. Compare modern two-strokes like Evinrude’s E-Tec outboards to modern four-strokes, and the difference is too close to call. Check our boat test database and see for yourself.

CONSUMER-Approved.

Evinrude outboard engines were ranked "Highest in Customer Satisfaction with Two-Stroke Outboard Engines in the U.S." in the J.D. Power and Associates 2009 Marine Engine Competitive Information Study.SM Receiving this award shows the benefits of owning an Evinrude E-TEC outboard engine.

Bigger engines. Bigger lead.

More displacement, more torque, more top-end than anything in the V-6 class. Yes, it’s the 250-hp H.O. and 300-hp. Evinrude E-TEC outboards. Featuring all kinds of powerful thinking including special high performance gearcases and advanced fuel injectors. Not just bigger, better.

More in the middle.

Our 130-hp and 115 H.O. V-4s. With a variable tuned exhaust valve to boost low-end torque and top-end speed along with a new cowling design to redirect airflow providing more power and enhanced performance. These engines pack a big punch.

SMALL ENGINES. BIGGER PERFORMANCE.

Our 13 engine options in the 25- to 30-hp range are light and tough, with plenty of electrical output and the slowest trolling speeds of any outboard in their class. Their ergonomically adjustable tiller handles give you more comfort and better handling. And their Fast Rise Inductive Ignition provides longer spark plug life and smoother running, while the mini blow-off valve will flush away most sand and other clogging debris for exceptional durability.
