I lost a blade
pulling into Grand Caymans in the middle of the night. I had to change out the prop because the blade was the same color as the coral and no amount of searching revealed it. I sent the prop back to Sweden (I think)and they said it was worn out and tried to sell me a new one. It was less than 4 years old, had about 4 thousand miles on it and only 'folded' (backed) a couple hundred times or so. I bought a MaxProp. The problem with Goris' dropping blades is because of the double set screw locking system. Leave one out or don't tighten one and the prop is done, and so is the boat. It is a good thing to have a 'collision bow'.
