Technical Comparison Analysis

Power & Displacement

Comparing the Parsun F9.8 (4-Stroke) and Mercury 9.8hp (Blue Stripe) shows a displacement difference of 29cc. The Parsun features a larger 209cc 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 30kg, offering a weight saving of 8kg 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 Parsun offers the best charging performance with a 84W 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.
