    What happened that broke the ride plate and intake grate?

    A faulty seal between the intake/ride plate/ water inatke can cause cavitation.

    I don't know what caused my ride plate to depart from my 750 SL either, but I do recall all of a sudden feeling a sinking feeling while riding, and then a severe loss of control and a top speed of about 30 mph. There wasn't a bump, jerk, or anything, but when I put the thing on the trailer, all that was left of my factory ride plate was an inch in the right front corner..... This happend years ago. Never damaged the hull.
