Go on phil go for the nearly new scorp.
But then again if the 8.5 has been more than kind to you this year in some big seas which I know you have been out in. Why not keep her and put the beast of a suzuki on the back or twin 200's.
Its a clean boat you have there, shame to sell her & its a heck of a lot more money to put up as you say for the nearly new one!
I would go the twin 200 suzuki option.
Scorp have come back to us now so maybe getting closer to owning one too!
