I have the same year boat , same motor and same jackplate. I am currently running a Fury 3 blade 24P with 3 open vent holes ( came with the boat along with another Yamaha prop as a spare). Fully loaded it takes about 4 secs to get on plane. I have owned the boat for about 4 or 5 months and I am impressed with how fast this boat will get out of the hole. I would love to hear from others who own the Z522 boat and what they are running too.
