Bass boy,
That transom is sweet. Hadn't thought of doing it that way. I see that you are an aluminum fabricator, what would a customer expect to pay to have some exactly like what you built fabricated for a similar boat. I'm just thinking that is going to cost a whole lot more than a sheet of plywood and some construction adhesive. (and maybe some epoxy if you're getting fancy)
It will cost more than a sheet of plywood, but is still worth it for many. Not only do you have plywood that can rot, once a little moisture gets between it and the aluminum, it often turns into a breeding ground for poultice corrosion.
I've quite literally pulled boats apart (the green one with the new transom pictured previously, for example) that were 'perfect' everywhere else in the hull, but once the transom wood was pulled, there was a huge mess of white chalky powder, and pits that extended almost all the way through the skin. That particular boat was still salvageable - only a few of the pits were very deep, so it required a fair amount of surface sanding, then an acid wash to clear all the corrosion. Then, the deeper pits get rewelded.
The high cost in a transom replacement is the removal and replacement time. If I was brought a boat that already had the old transom removed, and the owner was going to install my new transom - all I had to do was fabricate it, we're under $250 on most average 16' hulls. All the 'large' accessories (engine, etc) have bushings welded in for the mounting bolts.
It's all relative. If the goal is to refurbish a boat on a tight budget, these transoms probably aren't the right solution, but if someone is spending a pretty good amount of money building real nice aluminum decks throughout the rest of the hull, and plans to hang onto the boat for a while, it can certainly be justifiable.
