Trolling motor?

This may be the wrong place to ask sorry if it is.I have a min kota power drive that sound like it has a rod knocking it only does it when in the water and pulling the boat. any ideals or someone to talk to about it
Thanks

Might have something behind the prop

Sounds like one of the magnets may have come loose.

I took it apart and didn't see any thing but I don't know much about them.

Do you have a external transducer mounted on it? Have seen the cable get down where prop could hit it and it sounds like it's coming apart.

Armature is going out!!! Give H2o sports in sherwood Ark a call!!!! they can fix you up!!! 501-834-0998

I don't have any thing mounted to it. I bought a new edge but I hate it why I'm trying to see about getting the power drive fixed
thanks for the help
