I cant handle this!!!
In a normally functioning C208 just push the power lever as far as it will go to get over your imaginary obstacle. It will give you all its got and yes the engine will be a boat anchor when you are finished. Forget the EPL unless your FCU has died.
Secondly do not feather the prop. Even a windmilling prop will provide far more deceleration then a feathered one. Just ask the guy who bent a new Caravan at Caloundra a few years ago. Either way in this type of event the Insurance company owns the aircraft and you need to do what is required to save your butt.
