Sunil - I can go through most of our pond with my 76 lb thrust trolling motor but I try to avoid doing it, the trolling motor just makes cuttings of new milfoil and coontail clones so they can go root themesleves elsewhere. It defeats the purpose of spending money on treating the weeds.
A couple of years ago I did break the internal mounting brackets that turn my trolling motor when I had a 300 lb ball of weeds wrapped around the shaft.
