Seaman’s month in borders of Ecuador (7)

I believe the answer is:
mariner
'seaman's' is the definition.
(synonyms)
'month in borders of ecuador' is the wordplay.
'month' becomes 'Mar' (short for March).
'borders of' says to hollow out the word (remove centre letters).
'ecuador' with its middle removed is 'er'.
'mar'+'in'+'er'='MARINER'
(Other definitions for mariner that I've seen before include "Bluejacket" , "collier?" , "Seafarer, old salt" , "Person sailing" , "Jack" .)
