I've never started a diesel this way, but 40 years ago we started a 4
cylinder gas engine by letting the prop spin and slam it into gear.

Actually I didn't think it would work, but it did and we were able to
recharge our dead battery.

Of course I always thought you couldn't push start a diesel but then someone
proved me wrong by getting a couple guys and push starting a 2.5 ton Izuzu
truck.

I think the key is to have the engine properly tuned, timed and primed
before you attempt this.
