> Three screws; two of them (maybe all three) are Loc-tited in.

When I did this on my AFM  I could not find a Phillips head screwdriver that
fit the screw heads properly.  I would guess that the embossed lines radiating
out between each slot on the screw heads would indicate these are Pozi-drive
screws.   I got the screws to back out with a too small Phillips but I had to
get up on the deck above the engine and bear down quite forcefully.
The screws back out under constant tension and it feels like you are stripping
the head.  I just thought they were self tapping screws.   I hadn't even
considered that they might be Loc-tighted.
