Zodiac Inflatable Transom Water Discharge Orifice

[Pgutierrez]

I pulled my Zodiac inflatable out after 6-7 months storage.  When I pulled transom plug out, both the sleeve & plug came out as one piece.  I was able to separate sleeve from plug.   Plug goes into sleeve, sleeve should be attached some how to transom hole.  What glue should I use to glue plug sleeve into transom board??? Thinking of using gorilla glue on OUTSIDE of sleeve because it gorilla glue requires glueing surface to be wetted to fully activate the glue.  Looking at the interior transom hole surface (the sleeve gets glued some how into this orifice) I can't tell what material type I am trying to glue the plug sleeve into.  Your suggestions would be appreciated. 
Thanks.

The same thing happened to my Zodiac by West Marine.  I used 3M 5200 and it worked fine.  It's not coming out again !
