You might get more speed if you changed pitch on your prop.
i have a 16 foot polarcraft semi v john boat with the bare essentials like seat and trollin motor. i have a 25 horse yamaha w/ss prop that runs great on it but when i check my speed on gps it is only 22 mph. Is that all that should be expected or is there something i could do to get more speed?
