Technical Comparison Analysis

Power & Displacement

Comparing the Torqeedo Deep Blue 100i (100kW) and Mercury 125hp OptiMax shows a displacement difference of 1522cc. The Mercury features a larger 1522cc 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 Torqeedo is the lighter option at 85kg, offering a weight saving of 85kg 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 Mercury offers the best charging performance with a 864W alternator. Choosing the right power-to-weight profile between these two 0-stroke engines depends heavily on your specific boat's displacement and daily power requirements.
