After Yamaha screwed several thousand boat owners by not fixing engines built with non marine components that subsequently rotted out and prematurely ruined engines, I would be reluctant to purchase anything engines or otherwise made by that company.
If you plan to have a windlass, order the boat without one. Parker puts the windlass on the rear of the bow pulpit which is less than optimal as it does not drop the line over the deepest part of the anchor locker........not even close. Get a 22# Delta w/ 25 ft of chain and don't skimp on the swivel.
As said, "no" tabs are better than the 12x12s. If they are bigger now then fine. If not, then order without them and install later.
Get your livewell and some shade for the back from a local fabricator.
