I agree with your statement. I used the planned weight of the motor to plan battery position, live well position, and console position. I floated the boat with 240lbs of 5 gallon buckets of water to simulate the motor weight that planned out where everything need to go. Not required, but I didn't want to cross my fingers. The test made me realize that my big trolling motor battery needed to be as far forward as possible.
