    f 12x issue

    My f-12x runs smooth in calm water ,reaches 63-65 top speed with no issue,but if I hit a wave or jump it losses power and shuts off,restarts right away and it does it over and over.anyone that knows about this issue please advise me what to look for.

    The pump on these things comes unhooked easily. If you add an aftermarket intake grate you will loose 2 mph top speed but gain in overall speed.
    Some of the guys on here cut 2 bars from their grates and say this helps.

    Pump unhooks from water. Cavitation. The tunnel/entry design on the Honda was wide and the area just in front of the pump fills with air instead of water at the slightest ripple and they also porpoise a lot, (nose going up & down). It does not mean mechanically unhooked.
    Putting a scoop grate on the ski helps alleviate this but it will take you down about 2 mph. But the ski will not slow as much as when unhooking from water so your overall speed will be better. (60-50 mph without vs. steady 58 mph with, just an example, not exact numbers)
