The factory used silicone on the shoebox hull to deck joint.  It only lasts about 5 years,. Maybe less in salt water.  Not a great choice but was cheap and good for refurbishing.  Dig out the old silicone and add new.  
I on the other hand used sikaflex polyurethane flexible adhesive for below water applications.  I applied it inside and out with great results.
