Hi Guys...
Didn't forget about this, but I've had a bit of trouble geeting in touch with the guys at Grady. I did call again this morning and they are on an extended fourth of July holiday and will return next Monday.
I did look further into the potential access that could be gained by cutting the hole in the vertical side, and while it could get me the access needed for the through hulls, it doesn't look like that same hole will provide access to the outboard most deck drain. I'm looking forward to hearing what Grady proposes, cause I'm not sure I want to cut 2 holes...
Stay tuned.
BTW...ahill, did you get a chance to see what was on the other side of the 6" pieplate?
