Honda has sold 4-stroke outboard motors in the U.S. for forty years, leading the way in 4-stroke technology.

Why are 4-strokes better?

Lower operating cost

Four-strokes are approximately 50% more fuel-efficient than typical two-stroke outboard motors.  No two-stroke oil is needed, reducing your costs even further.

Better technology means longer life

  • 2-stroke engines rely on gas or air to carry a thin oil film to critical components.   4-strokes bathe every internal component in oil for consistent lubrication.  This design also helps cool engine components, which improves durability.
  • Ports in 2-stroke cylinders and pistons can accelerate piston and ring wear. Since there are no intake and exhaust ports in a 4-stroke cylinder or piston, they can operate with tighter tolerances for longer life.

More environmentally responsible

4-stroke outboards are approximately 90% cleaner than typical 2-strokes.  And 4-stroke motors do not release oil directly into the water.  

Honda outboards have ultra-low emissions.  All of our engines exceed the highest CARB 3-Star rating to meet the rigorous California Air Resource Board’s standards for 2009.

More pleasant operating experience

4-Stroke outboards are up to 50% quieter than 2-strokes.  Not to mention less smoke and smell.  No two-stroke stink to ruin your day on the water!
