Goodboat, mine was untouched from the dealer and running 72-73 gps. You will find some people raised jackplates higher, thinking it would improve speed/performance. The Classic/PII setup usually does not need a high jackplate setting, unless fishing extremely shallow, etc.If I remember correctly, my plate was about 1-1 1/2 inches above “flush”- where the inside/outside plates would be equally level.How is your torque, or do you have hydraulic steering?Taking your time, you should be able to get a solid 70 out of your rig…96 Eyra/12 Mercury 175 Pro XS with 2015 single axle trailer2017 Victory Gunner
