Technical Comparison Analysis
Power & Displacement
Comparing the Selva 100hp Spearfish (EFI) and Suzuki DF90 (Early 4-Stroke) shows a displacement difference of 118cc. The Suzuki features a larger 1950cc 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 Selva is the lighter option at 166kg, offering a weight saving of 23kg 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 Selva offers the best charging performance with a 420W alternator. Choosing the right power-to-weight profile between these two 4-stroke engines depends heavily on your specific boat's displacement and daily power requirements.
