One of my Gori blades is sunk on Grand Cayman Ils.
Had one, Loved it. BUT,,, make sure both inside and outer set screws are installed TIGHTLY or you will probably drop a blade. I did, pulling into Grand Cayman Island at 0400hrs back in '92. The bottom there is bronze colored so we couldn't find the missing blade. If you lose one side, NOTHING happens, no forward or back. You are back to just sails. I sent what was left back to Gori and they told me they couldn't replace a blade and would have to sell me a new one at full retail. They said mine was mostly worn out anyway. It went from Brownsville Washington (Seattle) through the Panama Canal and to the Caymans and they said it was WORN OUT! That is my experience. I bought a Max Prop. Still have it. Fred
