Bracket & Enclosing Transom Value Destructive?

[Erasmus4]

Merc says their 4S 150 weighs 455 and Yamaha says theirs weighs 480. So only a combined 50# delta. I believe the current ones are listed at 415, so the new increased weight would be 130#s (+16%) - hopefully solved by a bracket

After my current experience I'd prefer to never own Mercs again, so if I get comfortable with the weight increase, I'll go with the yams.

Has anyone on CSC run this setup on a 23 and able to comment on CG issues?

Lastly, has anybody put the new inline F200s on a 23 yet? Its pure overkill (am being quoted ~10k more for them) but since they are the same weight, it's fun food for thought.

Ryan, Frizzle, Thanks for your prior comments.
