i'm not here to compare trolling motors. minn kota makes a fine trolling motor and i am posting this to share my experience with them. i have owned 3 minn kotas. 2 of them were the all terrain series that i ordered from bass pro and the other was a bow mount edge series that came on my present boat. i bought the all terrains because of the composite shafts after bending the shaft on my motorguide. the first all terrain that bass pro sent me sounded like a siren when i powered it up. i'd never heard so much noise coming from a trolling motor in my life. i sent it back to bass pro for an exchange. and when i got the new one it was the same way. so i ordered another motorguide with a metal shaft. whisper quiet just like the last motorguide that i had. when i bought my present boat it came with a bow mount hand control minn kota EDGE model with a composite shaft. this motor too has a motor noise that sounds like a siren but not quite as bad as the all terains. i personally cant stand to be on my fishing spot and being as quiet as possible and hear my trolling motor making noise. we have a minn kota authorized repair shop here in town and i took the motor off my boat and carried it to the repair shop for an inspection. the repair man hooked the motor up in his special vise and turned it on. i could barely hear the motor run. i told him how it was noisey on my boat and he explained to me that the composit shaft transimited motor noise(he said that all electric motors made this noise) like a graphite rod transimited fish bites. he also said that the aluminum jon boat that i had it mounted on was like an amplifier with this sound. well guess what. i'm taking the sound transmitter off my amplifier and going back to those whisper quiet motorguides. they are little more expensive but to me quiet is worth it.
