I know this have been discussed a lot. I good friend of mine has a 2001 xb2003 with a 225 pro max. He's getting older and thinking about selling the boat which I may buy. I was concerned about the outboard weight restrictions that the hull could handle for future re-power. I was wondering if installing Lithium batteries in the boat would offset the weight difference of the heavier four stroke outboards. Seems like the difference in outboard weights are anywhere from 80-120 lbs. I know the weight location aren't the same. Just want to run it by you guys. Thanks.
