My sometimes cool job does pay off. If I work things right, I can occasionally get things X-rayed. Here's a shot of the stern tube, after the shaft has been pulled.

You can see the brass cutless bearing, and it looks like there are no setscrews at all. I have since hacked off the low density filler that was the lump at the aft end of the cutless, and can see the fiberglass tube around the cutless and the gelcoat of the original molded part of the hull.
The stern tube is visible as the lighter area around the cutless, looking kind of like a gauze bandage.
Anyone else with no setscrews? I'll post photos of the hull tomorrow. I did have a patch delaminated on the starboard side, and have cut that out.
As for the sheetmetal screws, they may have been glassed in as part of the build. Not too certain.
Used a home made puller to try to get the cutless out, no luck. I expect to saw the cutless in half or at least slot it to get clearance.
Cutless Bearing- No Setscrews?!

+1 for cutting the cutless with a hacksaw and spining it out with pliers. I had to take a cold chisel and make the bearing roll in a bit, then clamped it with vice grips and tapped it out with the hammer. Total time is about two hours.
A fair amount of gobbed up resin prevented my custom made puller from working, as the collet could not go down far enough to seat on the forward end of the cutless.
The PO had done the same slice technique, and repaired by gluing the bearing in with resin.

The new one is a light slip fit, and needs something to hold it better. A strong possibility is to turn up a bronze sleeve to fit over the end of the stern tube, and tap it in three places for setscrews. 2" OD by 1 5/8" ID is about right. I'd glass it in place.
