That has not been my experience. In my opinion there is no substitute for cubic inches and torque.
Last season I changed from a 26 foot boat with the 8.1 375 HP motor to a 27 foot boat with the 6.2 380 HP motor. The 8.1 seemed to have twice the acceleration and overall power, much more than the boat with the 6.2 that claims 5 more HP. The 6.2 is average at best and works a lot harder to get up and go. The 8.1 never even broke a sweat and even with 15 people on the boat I could hardly tell the difference in performance.
