Then why do big 4 stroke OB's have to turn higher rpm to develop the same
HP?


Care to cite an example so that I know what you are talking about?

Be careful when comparing any two motors, no matter if you are comparing 2
cycle vs 2 cycle, 4 vs 4 or 2 vs 4. Too bad that the manufactures don't put
the torque curve in the sales brochure, then you could really see how the
motor rates!
