Technical Comparison Analysis
Power & Displacement
Comparing the Scott-Atwater 5hp Classic and Mariner 5hp (2-Stroke) shows a displacement difference of 19cc. The Scott-Atwater features a larger 122cc 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 Mariner is the lighter option at 21kg, offering a weight saving of 0kg 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 Mariner offers the best charging performance with a 60W 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.
