Can't say for sure how much difference it will make on your hole-shot, but it's that much less weight the motor has to lift out of the water before the boat planes so there will be some amount of difference which will also be a function of your motor power and prop pitch etc... You can certainly test it fairly easily before you wire it up.What's more important is the stress that much torque puts on both the boat hull and transom.Imagine holding your arm straight out in front of your body and trying to support the battery in that position let alone lift it up 3"-6" (approximately the amount of hull rise in the bow when on plane) - now imagine extending your arm 10' out from that position and lifting the battery. While this is a crude example I'm trying to point out just how much torque is transmitted through the boat-hull and transom having weight forward that needs to be lifted out of the water to get on plane and stay on plane. That stress runs through the rivets and through the welds and will only be made worse on rough water.Before kids I would use my boat 5 times a week during the open season, I'm hoping to get back toward being out at least 3 times a week next year - so that amount of stress would quickly wear on my boat and was a major concern to me when I was building it. I've been through a leaky rivet patch job once and I'd rather avoid having to do it again as long as possible.
