John, I think you're right about the I/O models sitting a little lower in the water, even on plane . . . if you look at that Boating Magazine article I sent you of the tests of the I/O and OB powered Tsunami's, they had a good shot of both lightly loaded boats running together at high speed and you can clearly see the chine at the transom of the OB model! Looks like the entire outer panel was dry! The OB model had twin I-6 Mercs and the other had twin 165 I-6 Mercruisers, so the OB model would have been much lighter. Interesting that the min running angle on the I/O was a little flatter (3 degrees vs. 4 for the OB), so either the extra weight is enough further forward to shift CG further forward on the I/O, or what's more likely is that the power trim was more effective at controlling running angle on the outdrives than on the outboards.
BTW, I still have a .pdf file of that excellent 9 page article. Will be glad to forward it to anyone that wants a copy if you'll just PM me with an e-mail address. Denny
