Terry - great post that lots of guys should find very useful! Even if the absolute value of the some items isn't real accurate, like CG location of bare hull, it will still be be pretty close at predicting CHANGES in CG for changes in one or two items, like a motor or bracket, provided the numbers for the questionable item remain constant!
After someone uses Terry's method to figure out how much the CG will shift with a given repower option, they can then use this method to figure out how to create the same CG shift on their current rig using ballast (a cooler or trash can filled with water) in the back of the boat, and then go test it to see what effect it has on the boat's ride, handling, min planing speed, etc. and confirm what I've been trying to tell folks for several years in my post on the Pro's & Con's of Brackets!
Moderators - I think this one is worth making it a "sticky" in the Repairs/Mods section! What say ye? Denny
