For my usage, 40lbs would be perfect. But I troll along banks for pitching crappie and bass and issues like that. Rarely do I troll for very long extended periods with just the trolling motor. So my answer is YES, but it depends on how YOU troll. Others may find it too small. I don't need the most powerful latest high output trolling motors I see these days for sell. As you move up in the trust ratings you also use more amperage, needing motor battery power and even higher voltages (two or three batteries). That is just my 2 cents.
