Center of gravity location MA20?

[Chaser]

I did some digging back through some other threads and think I got the info I need. Looks like the center of the old tank should get me close, around 63%/12' aft of the bow.

I'm repowering with a 135 or 150 4 stroke (I know it's heavy I'm going to deal with it). Originally I thought moving the fuel tank forward was a good way to balance the weight of the heavier outboard. But then I though that would change the trim depending on the amount of fuel in the boat... So I think I am going to put the new tank right over the CG and shift the console a little bit forward.

The new cockpit sole should be about half the weight of the old, same with the new console. That will eliminate around 150-200 lbs (those old consoles are heeeeaaavy!) and that should all help a lot. I am also going to leave a space to add ballast forward under the sole to adjust the trim once the boat is all back together and I see how she sits.

Pulled the old sole out yesterday, as well as about 50 lbs in wet foam, mostly from the aft section. So I'm thinking the boat will sit simillarly to how she sat before, even with the extra 100 lbs of outboard back there. May not need much ballast if any at all. But, since the boat will be significantly lighter than it was, adding a little ballast to make her float even shouldn't be the end of the world.

Will post pics as the project progresses.
