I’m getting ready to add a trolling motor to my Dave Scadden Detonator Lo Pro X. Trying to decide on the Minn-Kota Endura 30 (30lb thrust x 30” shaft) or the Minn-Kota Endura 40 (40lb thrust x 36” shaft). I plan on fishing medium-large lakes. Leaning towards the Minn-Kota Endura for more thrusting power but afraid that it’ll run the battery down faster. Please help me choose wisely, give reason for why one over the other. Thanks you guys, great group!
