Deliberate detuning. Possibly smaller carb, different head etc.

The Tohatsu comes in a 2.5 and a 3.5. Probably using the same block on both
to save production cost. Several 9.9's use the same block as the 15's in
the same line.

Next size up in the Suzuki line is a 6HP. No savings there so they squeeze
all the power out of the smaller block.

Sorry all, I should have been more specific since there are apparently
not too many generic answers to the questions.

Okay, here are the two motors I was thinking about when I posed the
question.

++2008 Tohatsu/Nissan MFS 2.5 hp with 85cc motor.

++2008 Suzuki DF2.5 hp with 68cc motor.

The Tohatsu has a 25% greater displacement yet the Suzuki is rated the
same horsepower (2.5) as the Tohatsu.
