Technical Comparison Analysis
Power & Displacement
Comparing the Johnson 115hp (4-Stroke) and Chrysler 105hp (2-Stroke) shows a displacement difference of 368cc. The Johnson 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 Chrysler is the lighter option at 113kg, offering a weight saving of 76kg 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 Johnson offers the best charging performance with a 504W 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.
