Merlin may have the right idea: Don't do anything you don't have to.

That said, it just depends on what tools you want to use. A small circ
saw with a carbid blade can cut the top corners off the logs freeing the
top and the top edges of the sides; if you have an power plane with old
blades you don't mind wasting, that will take the corners (or the whole
top) off, too. Then you pry remaining glass off with a flat bar. A recip
saw with a long flexible blade with a few large teeth can be laid flat
against the hull to "flush cut" the bottoms of the sides. Again, a flat
bar will take the rest. If you don't like a recip saw, a wide sharp
chisel and a hammer will cut the inside bottom corners along the hull -
and no dust! Get a diamond sharpening "stone" to put your edge back on
the chisel. A chisel can also take the top by cutting straight on the
top a 1/4" along inside the sides - then pry up the glass on top a
little and use the flat bar. Pry the other way and get the sides free.

But if it's built like brick **** and solid as gibralter, why not just
use it to build on? If you need to lower a section, use a power plane
with the exhaust port hooked to a shop vac to take it down as far as you
need; discard the planer blades after. Then disk sand the sides and
epoxy more glass over your new top surface.

My understand has that it's better to bolt rather than lag the engine
mounting (to the logs), if possible. This can often be done by bolting
hefty angle channel to the sides of the logs, with the "flat" side up to
carry the (bolted on) engine mounts. _Heavy_ mild steel angle works well
and will cut and drill easily; it will look better longer if it's preped
and painted nicely after drilling, before installation. Clamp solidly in
place to mark holes and cuts. If you mark it, most shops will cut and
drill for a few bucks a hole.

If the rot is just around the lag bolt holes, why not cut them out with a
hole saw and fill with epoxy and filler instead of replacing the entire
wooden stringer?

Hi,

Just removed the old engine in Far Cove and started rebuilding the

stringers.
