Hey guys, recently purchased an old outback, been taking it out wakeboarding this week and the wakes actually been great but keeping speed isnt easy anyway does anyone know how the speed calibration works? Its a little black controller next to the throttle and it has left, right up and down, not really sure how it works or how it would work because i dont recall seeing trim tabs on the boat.

Also i have a 4 blade prop thats on it right now, but i also have a 3 blade 13x13 and i heard its common to use this prop for waleboarding and wakesurfing, would changing props help maintain a more steady speed? Thanks.
