Autoprop vs...

I've had an Autoprop on a IP 40 for 4 years and have found it to be an excellent product. Bought it for it's ability to vary the pitch. Stopping/Reverse are vastly improved over the fixed prop. Boat speed is up about .5 k under sail. After initial install there was some vibration. Did some Speed/RPM tests for Autoprop. Sent it back to their factory they returned a corrected prop.(all on their dime). I know they changed design about 8-10 years ago to a greased bearing from a water lubricated one. Have not heard of blades "falling off" first hand. I did purchased an adapter to hold an off the shelf zinc as the AP Zincs are hard to find and expensive. You will also lose the prop walk, which on a long keel will make reversing at low speeds interesting. I sail Long Island Sound where there are lots of lobster pots. The keel, skeg, rudder setup that's on the IP40 is terriffic. I haven't wrapped up yet.
