Since I just paid a substantial amount of money for a new prop, I am looking for a prop lock. It seems like the McGard is by far the most common when I search online. There are a couple of videos on Youtube of how to quickly defeat a McGard lock with a screwdriver and vise-grip pliers. Therefore, I am wondering if anyone can suggest an alternative that is more secure? This is for a Tohatsu 50HP. Thanks.
