just bought my first jet ski. a 2004 fx 140 with 40 hours. i had it out for first time over the weekend. the fastest i got the ski was 48 mph, is this normal or is there something wrong because i was expecting it to be faster..

53 is top speed on the FX. Did you check your speed by GPS. The on-board speed sensor on all skis will typically be off as much as 5-6 mph.
