3rd vote for Atlantis in Mt. Laurel, NJ. Tom, the owner, is a super guy. They are a PropScan shop. BTW, you can borrow a prop puller from Duffy's and leave your props there for Atlantis to pick-up. They'll call you with the results of theie analysis and the cost to tune before they do anything. Tom will want to know your boat, tranny, RPMs at WOT to make sure he gets them perfect. After they are done they'll deliver them back to Duffy's for you.
