IMO, better to learn to hove-to and tuck in a main reef than to rely on a motor.
Start on port tack. Tack over to port eg. onto starboard tack, but DON'T release the jib sheet. As the boat blows off due to backed jib, put tiller over to port, or steer wheel to starboard. Whichever, the rudder will be turned to starboard, such that the boat is steered to windward by rudder, but backed jib blows it back off the wind. The boat will then slip moderately downwind in a scalloping fashion.
You will also have to let off the mainsheet to relieve pressure on the main, as you loosen the halyard, and drop main to first reef point, then fasten tack as your reefing was designed (several different methods) and then tighten clew reef line. Or, you have single line reefing, and pull that tight to effect the reef.
When you're all done reefing, just free the backed jib sheet, re-sheet on other side, sheet in main, and steer away on your course.
Easy peasy, calms everything down, and no motor required.
