Boat propeller made good liner turn bad (9)

I believe the answer is:

gondolier

I'm a little stuck... Click here to teach me more about this clue!

'boat propeller' is the definition.
(I've seen this before)

'good liner turn bad' is the wordplay.
'good liner' anagrams to 'GONDOLIER'.
Though, I'm not sure how this is indicated.

'made' is the link.

Can you help me to learn more?

(Other definitions for gondolier that I've seen before include "Venetian waterworker" , "to leave Red Lion disorientated" , "Venetian boater" , "Punter" , "One to move over water" .)

I've seen this clue in the Sydney Morning Herald.
