Just bought a new motorguide bow mount pro 24volt 70lb thrust from bass pro. Put it on last night and tried today for first time. The first time i tried it today it made a constant knocking noise. I traced the noise to the prop and it moves in and out enough to make the noise. Prop was tight and on correct. Stopped at bass pro on the way home and was told the bearings are shot and i should have bought a minn kota. The only thing is some of the display model props moved in and out as well.<br />Has anyone else ever had this problem with a motorguide or any other for that matter. <br />Going to return this week if possible do you guys swear by motorguide or minn kota<br />Thanks diggs
