not real silly. when i had a pwc. i disconnected mine. some for not wanting to draw attention to myself. but also because i didn't want to get wet from it. i usually ran out the season on both ends. spring and fall in neb. can be cool out weather wise for jet skiing and getting wet wasn't desirable for me..but that's my main reason for not wanting one silly as it may sound.
Oh so it's not useful at all and can be disconnected?
I always figured it was for visibility, but I also thought it was the exhaust for cooling water, sort of like how an outboard pees.
Very silly indeed too. Though it can be funny when pulling away from a beach...
I've always wanted one cause they do that, good to know its pumping water too.
I rode several Sea Doo brand sleds even one that was supercharged I never noticed a telltale on them.
Funny name for it.
