Faster - From reading other threads, I believe annual maintenance may be required for the AutoProp. Regarding MaxProp maintenance, re-lubing is recommend every 2 years, as per the following from the PYI web site . . .
The Max-prop needs to be degreased a minimum of once every two years. We recommend Lubraplate “130 AA” grease.
There are two holes in the spinner of the propeller to grease. Remove the set screw from the forward holes with a #3 metric Allen wrench and screw in the zerc tower, attach your grease gun and fill the propeller with grease until the grease starts to come out between the hub (1) and the spinner (7). Replace the set screw and remove the set screw from the more aft hole. Reinstall the zerc tower and attach your grease gun and fill the propeller with grease until the grease starts to come out between the blades and the spinners. Remove the zerc tower and reinsert the set screw into the propeller. Do not leave the zerc tower in the propeller.
• With each pump of the grease gun rotate the propeller from forward to reverse to allow the grease to work through the propeller.
• The numbers above are from Figure 2 at the beginning of this Max-prop Manual
• Make sure that you always keep the zinc anodes in good condition. They must be replaced at least once a year. The propeller must be protected by a lot of zinc, so also use a zinc on the shaft when possible. When replacing it make sure that you clean the contact point between the zinc and propeller. Use a wire brush or fine sandpaper to clean the aft of the end cap and the forward face of the zinc to give the zinc good contact with the propeller.
