I purchased a 2002 lund rebel with a 40hp yamaha 4 stroke. The boat has a steering wheel and forward controls. According to my gps with just me in the boat it will do about 27-28, with two pple in the boat it will do 25-26 does this seem about right? I figure boat weighs about 1500 or so the way it sits. I have a tach coming this week so i dont know for sure how fast the motor is running but it does have a 13p prop on it and it seems kind of sluggish out of the hole. I knew this thing wasnt going to be a speed demon but just want to make sure this sound about right for the size of boat and motor. Thanks
