Feather....... FLY THE PLANE !
With luck, you'll fly it out straight ahead and gain a few hundred feet
before your good engine overheats.
What has bothered me since initial multi-engine training is that the commonly taught procedures assume that an engine has just two states: "good" or "duff". The procedure caters for the case where a catastrophic engine failure occurs and an immediate shutdown is necessary.
Real life isn't that straightforward, is it? Even if you lose all but 20% of the power in a malfunctioning engine, that 20% might double the excess power available to give the aircraft a sensible airspeed and rate of climb. In an aircraft that is marginal on a single engine, that can make a huge difference to the likelihood of a safe outcome.
