I have a 2005 Challenger 180 (215hp), and depending on the impeller, it runs 45-48 consistently. With the stock SeaDoo impeller, it holds at 45 on glass or small chop. With the Solas Concord I had in it before, it topped at 48, but I had cavitation at launch. These speeds are from the Garmin GPS mounted in the boat.

Hit 52 with my 09 255 HP on a GPS unit. My speedometer is way off and the dealer is checking with Sea-Doo since I already changed the pick up on the outside of the boat. Should be able to squeeze a little more out of it on a calmer day.
