OK heres the deal .... I have two older MG trolling motors ..... Both are ss shafts .... Both are around 70 lb thrust / 24 v systems .... One has a bent shaft & has been sitting on my shelf like that for over 10 yrs .... The other is on my boat & to be honest has always seem louder than normal .... I'm thinking I should update before I retire here in the next year or so .....The one with the bent shaft worked fine when I put it up .... Thought Id ask here what you guys would recommend before I looked into putting new shafts in my back up ...
