Something doesn't sound right with your set up. Bass and Walleye tested a 620 with an Pro xs and the boat went like 63mph with out a jackplate. They were running a 24p Lab finish four blade prop and for some reason I believe that had a racing lower unit on the boat. The setup they had had the best performance of any of the 250hp motors that were tested. Running 59 mph is not bad , what kind of load was in your boat.
