I bought a trolling motor tonite and when i got home i had a totally different model than the one that I bought. (Kid At the store loaded wrong one) I thought I was getting a motorguide digital series and when I got home it was a wireless series. are these good motors?? my old troller was a mercury thruster plus and it ran great 4 25 yrs. cant seem to get parts and i guess its time to upgrade? If these arre quality motors then maybe i should keep it, if not i need to exchange it,the prices were the some and its a hour and a half drive to where i bought it. Comments and opinions please!!!!??!!
