I had a Minn Kota 12' Talon professionally installed approximately 1 1/2 years ago. Recently I am hearing an irregular but consistent knocking/thumping noise while anchored. The Talon deploys and retracts without any problems or unusual noises. The sound only occurs when anchored. I spoke to Minn Kota and sent them a video with sound and they do not know what the cause is and recommended getting it to an authorized service provider. I am hoping someone has experienced something similar and advise me as to whether this is a problem or not as I am hoping to not have to haul the boat to the nearest provider.
