Since propulsive_power is proportional to velocity, and velocity is basically unlimited (i.e. I can define a reference frame in which the aircraft is moving near the speed of light), the efficiency can be greater than 100%! It took me a long time to figure out the solution to this paradox. I will wait a bit before posting it, so the readers can have the fun of figuring it out.
