    The overall shape of the board is created from the factory mold.  Unless there was signifcant damage at some point, the outline should be fine.  The centerboard section profiles are controlled by a maximum thickness which is 1-3/8″.  The section profiles cannot be modifed from the original factor mold shape which puts the max thickness at the midpoint (50% chord) of the section.  If the max thickness is at the 1/3 point, then the board is illegal, but based on the photo it appears to be at the midpoint as it should be.

    West System 6-10 thickened epoxy will make this very easy.  It is thick enough to stay in the holes without the tape and cures quickly.  I would still tape on the outside to avoid a mess.  Gelcoat repair is also easy, especially with a white hull.

    Some lubricants can cause plastic to swell.  This may be the root cause of the problem.  many of the newer pole end fittings are plastic, though hard to say what type.
    Here is some info regarding compatability of plastic and lubricants:

    The best bet may be to avoid lubricants altogether and just use water.  
    Hard to say if the pole end can be saved once it has swelled.
