For bedding nonstructural items like ports, a good marine silicone
like 3M or Boat Life gives good service. 5200 should be used only on
permenent applications where there is no forseeable possibility of
removal.
From thru hulls to hardware bedding, I have found polysulfide caulks
to be best all around material.
