Over a season, the fuel savings can be substantial.
Mercury: Mercury has made massive strides in efficiency with its FourStroke and Verado lines. Their engines are highly competitive, but they are generally optimized for power delivery first and efficiency second. For a given horsepower, a Mercury will typically use slightly more fuel than a Honda, especially under heavy load or at high RPMs.

Noise & Vibration Levels

A quiet engine reduces fatigue and lets you enjoy the sounds of nature and conversation.

Honda: Honda is the undisputed industry benchmark for quiet operation. Through extensive use of rubber isolators, precision gear design, and sound-absorbing cowling materials, Honda outboards run at a whisper. This is a huge benefit for anglers sneaking up on skittish fish or families enjoying a peaceful cruise.
Mercury: Historically louder, Mercury has invested heavily in quieting its engines. The Verado series, with its integrated sound-dampening system, is remarkably quiet and has closed the gap significantly. However, in side-by-side comparisons, Honda typically maintains a slight but noticeable edge in decibel levels and vibration dampening.
