FWIW, SC, the 5200 or Sikaflex or whatever sealant
you chose does not hold the throughhull in place, it only seals
up the small clearance between hull
material and the fitting. The large nut that you tighten up on the inside of the hull
is what holds it in!
Thus, the strength of the bond of the sealant
is not so important, and the 5200 (IMO) is overkill that will frustrate you in the future should you need to remove the fitting.
But, the job is done now, so enjoy your new instrument and your sailing.
