Technical Comparison Analysis

Power & Displacement

Comparing the Suzuki DT25 and Tohatsu MFS25 (Early EFI) shows a displacement difference of 27cc. The Tohatsu features a larger 526cc 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 54kg, offering a weight saving of 17.5kg 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 Tohatsu offers the best charging performance with a 180W 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.
