Hello to all,<br /> I have a Brute 750 12/24 trolling motor that is really making so loud noise. I tore it down last night to look at the innerds,the brushes(4) are grooved somewhat,I cleaned them up and the copper facing that they ride on, then reassembled, this took alot of the noise away but not as much as I would like. I'm looking for suggestions now.<br /><br /> Thanks,<br /> Boo
