I have a'17 foot aluminum boat with 70 4 stroke. I have a lowrance unit at bow and will if it goes bad I will likely replace with a garmin. I want a pull cord sizzor type motor deploy and stow motor. I want a motor that has a transducer built into the foot and no exposed wiring on outside of shaft. I want gps anchor and maintain course features. I'm looking at minnkota ultrex, motor guide tour pro and lowrance ghost. Please offer your opinions.
