Technical Comparison Analysis

Power & Displacement

Comparing the Yamaha 6hp (2-Stroke) and ePropulsion Navy 3.0 EVO (3kW) shows a displacement difference of 165cc. The Yamaha features a larger 165cc block, which typically provides superior low-end torque and better hole-shot performance when pushing heavy loads or reaching planning speeds.

Weight & Rigging

In terms of transom weight, the ePropulsion is the lighter option at 24kg, offering a weight saving of 3kg over its competitor. This weight reduction is critical for smaller hulls or boats with limited transom capacity where every kilogram affects the center of gravity and drainage efficiency.

Electrical & Features

For boats equipped with modern electronics, sonar, and shallow-water anchors, the ePropulsion offers the best charging performance with a 660W alternator. Choosing the right power-to-weight profile between these two 2-stroke engines depends heavily on your specific boat's displacement and daily power requirements.
