Re: Dauntless 160 Data Yamaha F90 vs F115

Boat speed is generally proportional to the HP-to-weight ratio to the 0.5 exponent. If you increase horsepower to 115 from 90, and the total weight remains the same, the boat speed would change according to a ratio of (115/90)^0.5 or 1.13:1. If the 90-HP speed was 34.4-MPH then the 115-HP speed shou...
