Another good question? What kind of slip numbers are you guys running? I dont have that much experience with these boats either and am still learning. Maybe this is normal.....but in my boat I can hit the rev limiters with 4 people, fuel, cooler etc.. just as fast as I can with just me in the boat. The difference is the speed but rpm stays consistent. I trim the boat the same every time...Level with the bottom to get the rpms up and then slowly touch it down to negative trim.
