How to replace Gori propeller blade stops WITHOUT removing prop blades

Here's a quick video of one of our maintenance projects while the boat is out of the water. We had been told in the past that this is not a job you want to tackle while in the water - and boy, were they right! I couldn't find a how-to video or any visual instructions on how to do this, so hopefully this video will be useful to other sailors. Removing them with a flat head screw driver is fairly easy. Inserting the new ones is tough, and took some trying before finding a technique that worked without getting fingers mangled. If you have a sewing palm handy, or any hard surface you can fit in the palm of your hand without slipping, this job becomes very doable. Enjoy!
