What's up with the display changing over to metric after 170 hours on my '03 GTX 4tec? It seemed strange when, for no apparent reason the "!" alarm went off the other day at the dock after riding 20-25 miles w/o any problems. My friend had this on an 06 ski when it was new, so the dealer reset his display. My ski displays analog dials for mph, rpm of course, but all the digital stuff has gone Klondike on me. Ski runs like new and came with the mode/ set buttons near the start button. It has the set-up to switch between water temp, air temp, average speed, actual speed, elapsed time, etc. Some or all newer skis don't have any of this stuff?
