My prop to pad distance is -3″. Boat performance is awesome! When I look at the top of my 6″ slidemaster for reference, the top of the outside channel is approx. 1 1/2″ above the inside channel thats connected to the boat.Ive read a lot of threads and most talk about the top of the two channels being flush or the outside channel being a little above flush.Im guessing that my motor is mounted low on the jackplate compared to others? Which of the engine top mounting holes is normally used?Thanks!
