You really need some knowledge of the torque curves to answer that question. Assuming the 200 develops more torque at the same or lower RPMs, it should be able to spin a prop with more pitch and get some extra speed or run at lower RPMs. Running at lower RPMs should be good for engine durability, but assuming it takes the same horsepower to run the same boat speed, fuel burn would be about the same. The torque drops off rapidly on the Yamaha V6s below 4000 rpm. |
