Thank you for the answers, really appreciate it! Just curious about bigger/heavier boats. If for example the wet weight of a boat (deep v hull) is around 3300lbs and has a 100lb trolling motor the ratio would be the same as in my case (3 lb vs 3 lb of every 100lbs). I know that these recommendations about thrust are not that sufficient, but I guess they tell something or am I totally wrong?
Would my trolling motor/boat fight the wind or current as good as the bigger one? Obviously the bigger one has more thrust/power but the weight/size of the boat is also on another level compared to the smaller boat.
