A 'saildrive' is an inboard engine coupled to what is essentially the lower end of an outboard drive unit.. the drive extends straight out of the boat at the rear of the engine.
Direct drive, or shaft and strut, has a propshaft extending aft from the gearbox, penetrating the hull at a shaft log/stuffing box, usually supported on an extended strut just ahead of the shaft mounted propellor.
