Technical Comparison Analysis
Power & Displacement
Comparing the Mercury 135hp V6 OptiMax and Oxe OXE125 Diesel shows a displacement difference of 507cc. The Mercury features a larger 2507cc 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 195kg, offering a weight saving of 155kg 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 Oxe offers the best charging performance with a 1872W 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.
