I was in the market for a new trolling motor to put on a 18ft bass boat and was wondering about the new 12 volt motors. They claim to last longer and have more thrust than before. Anybody have one of these? My boat currently has a 55lb thrust 24v system rigged. Old motor seems to have lost alot of thrust over the years. Is 70lb just overkill in 24v? Or should I try the 12v 55lb. Tell me what you like any info will be helpful. Thanks
