🛠️ Service Notes

• The cone is part of the propeller assembly, so only work on it with the drive shut down and the propellers safely immobilised, and ideally with the boat out of the water
• Clean the shaft, the cone seat and the threads, and check the seat and any bushing or ring for wear, cracking or corrosion before fitting
• Fit the cone with all of its original small parts — washer, ring and nut arrangement — in the correct order, renewing anything damaged or corroded
• Tighten the retaining nut to the figure and by the locking method given in the workshop manual for your drive, and confirm the lock is properly engaged before the boat goes back in
• Check the cone for security at each haul-out, and look over the anodes and shaft seals while you have it apart
