The holes are round so I think that's just the camera angle combined with
the shadows in the holes. Turned out it was not the plywood delaminating,
the delamination was at the fiberglass/plywood intersection. The glass
was thicker than I expected, about 3/8" or so. I've removed some of it
and still need to feather the edges. The plywood is in so so condition.
A bit punky on the top layer with one softer spot on the left side. To be
expected after 18 years I imagine. I'll post another picture after I
finish grinding. I'm once again remembering why grinding in the garage is
not such a smart idea, dust EVERY FRICKING WHERE. Have to drag it out on
to the driveway before I feather the edges. I'm going to go ahead and
remove the area under the lower third of the outdrive as well. Now that I
think about it more, creating a joint right at the bottom edge of the
outdrive is not such a smart idea.


You are probably aware of this, but I thought I'd pass it on anyway.
If the plywood isn't so bad that it needs to be cut out and replaced,
saturating it for a while with automotive type anti-freeze before doing the
fiberglass repair is supposed to kill the organisms that would continue
the rot and prevent it from rotting further.

That's what I've read anyway.
