All Flexofold propellers are shipped with pre-applied under water Loctite.
Yes, all Flexofold propellers are shipped with pre-applied underwater Loctite, which allows for underwater applicaton. This Loctite is different from that which can be purchased in a hardware store, which will not cure underwater.
Once a screw with pre-applied Loctite has been used it won't work a second time underwater. Find new screws with pre-applied underwater Loctite in our Spare Parts Section.
