Atlantis is a PropScan shop as is Wildcat. I had mine down by Alantis several years ago and I highly recommend them. In fact, after seeing the diference between old school hand tuning and computer tuning I wouldn't have my props touched by an shop that doesn't use computer analysis and tuning.
Call Atlantis and make an appointment. Then you can walk in with your prps and they'll put them on the machine for analysis while you wait. Withing 30 minutes you'll have a printed report of what the props look like and a plan to tune them. You will need to supply them with boat specs (boat make, model, engine and trans specs, current RPMs at WOT, do you want more economy or speed, etc). The more info you can provide the better they can tune them for you.
