Out of bounds, perhaps, drive ultimately hooked? Totally incompetent! (8)
I believe the answer is:
hopeless
'totally incompetent' is the definition.
(hopeless can mean completely incompetent)
I don't understand the rest of the clue.
(Other definitions for hopeless that I've seen before include "Despairing, pessimistic" , "With no chance of success" , "incurable" , "Inefficient" , "Despairing - pathetic" .)
