In this video there are a few runs from 2 angles. One watches the speedo and the other watches the front end of the ski. When the water comes over the front of the ski on the 2nd run from the speedo angle, is when the brake is hit. The ski hits 72MPH with the camera on. 73MPH when the camera is on the front angle. But the Sea Doo has a top speed mode which holds the top speed recorded. I hit 75 and got the picture on the camera. This is amazing 75 MPH!!! And even better if you watch in 720p HD. Please enjoy this video. Watch the needle move it unbelievable. The 2007 RXT in the background set off at the same time as me, and you can clearly see the difference. The music is off Tiesto’s new podcast. I do not own the music. It is in miles per hour NOT knots or kilometres per hour. I believe that the ski is going 120.7 KM/H The speedo is controlled by GPS. Therefore is accurate.
