DID YOU KNOW - that correct use of tab washer and shaft nut locking screw (with pre-applied underwater thread locking compound) is essential to prevent potential loss of the propeller?
When mounting a FlexOfold propeller on a saildrive, ALWAYS use original tab washer and locking screw! As per photo, the tab washer must be bent over the nut as well as the head of the locking screw. Failure to make both bends risks losing your prop!

Parts FAQ
Are FlexOfold parts interchangeable across propeller families?
No. Many anodes, cover plates, service kits, shock absorbers, nuts, and washers depend on blade count, shaft/saildrive family, and part number.
Should I buy parts before haulout?
Yes, if the part number is known. For unknown parts, gather photos and markings before haulout so the right parts can be ready.
