Technical Comparison Analysis
Power & Displacement
Comparing the Evinrude 135hp Crossflow V4 and Mercury 125hp (Inline-6 Tower of Power) shows a displacement difference of 35cc. The Mercury features a larger 1635cc 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 Mercury is the lighter option at 135kg, offering a weight saving of 7kg 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 201W 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.
