Technical Comparison Analysis
Power & Displacement
Comparing the Suzuki DT140 and Yamaha F130 EFI shows a displacement difference of 59cc. The Yamaha features a larger 1832cc 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 Suzuki is the lighter option at 165kg, 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 Yamaha offers the best charging performance with a 420W 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.
