Please suggest an intake grate for my Sea Doo GTS which we use on a choppy lake. I wish to preserve as much top end on calm water as possible. However, cavitation in rough water is a real problem.
I am considering one of the following: A Westcoast intake grate, and R&D Aquavein intake grate, or Jet Dynamics grate.
For rough-water riding you need a top loader intake grate to push the water into your jet pump. Be aware that these intake grates will reduce your top speed 1-2 mph in smooth water. All of the brands you mention are good quality grates. I wouldn't hesitate to put any of those on my craft...
