Thanks a lot for the replies. I still have not purchased the autopilot unit as of yet. I did purchase 2 simrad go 9 one for sonar the other for gps and possibly linking for auto pilot. I was leaning tward simrad ap44 autopilot. However I’m still not sure due to so many that like the Raymarine. Finchasher if you have any pictures of setup,and what pump,you used , that would b great.
