Leave my boat outta this
Just get yourself some 750 lb fly-high ballast bags for the rear, a 400 for the front, a couple of pumps for now and go to town!
My 2003 Outback DD produced a darn good surf wake, your OBV will do even better.
Oh...and of course everyone expects me to make this statement:
if you can locate a 2009 Outback V for a few grand more - grab it. Night and day difference.
An LSV is a pretty good boat too!
