Try an old broken boat (7)
I believe the answer is:
gondola
'boat' is the definition.
(I've seen this before)
'try an old broken' is the wordplay.
'try' becomes 'go' (go is a kind of try).
'broken' is an anagram indicator.
'an'+'old'='anold'
'anold' with letters rearranged gives 'ndola'.
'go'+'ndola'='GONDOLA'
(Other definitions for gondola that I've seen before include "Venetian taxi" , "Venetian boat - airship cabin" , "It's traditionally used on the canals of Venice" , "narrow boat" , "Venetian transport" .)
