Technical Comparison Analysis
Power & Displacement
Comparing the Tohatsu MFS50 EFI and Chrysler 45hp (2-Stroke) shows a displacement difference of 175cc. The Tohatsu features a larger 866cc 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 69kg, offering a weight saving of 26kg 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.
