Quick stop method. 

[MOB QuickStop (YouTube)](https://www.youtube.com/watch?v=88kq6iZMNM4)

Watching this video will not enable you to do this when you actually have an MOB. Like any other aspect of boat handling, it must be practiced continuously.  As compared to any other aspect of boat handling, it's as critical as tying a knot or turning on your motor. The odds are small but the consequences are steep.  

Again - there is no substitute for practice (use a cushion, not a person though ;)
