The test is whether or not you are "operating mechanical propulsion". Engine on, you're a power-driven vessel. Doesn't matter what you have hanging from your sticks, or whether or not your transmission is engaged.
And I suspect that shutting off the engine just before the collision would probably NOT make you a sailing vessel in the eyes of the admiralty court.
