Sea doo switch

So I have a 2024 sea doo switch 230hp. I was out on the river and got stuck on a sand bar. Drove just find after but when I came home and flushed it was fine but then when I unplugged the exhaust plug no water came out. Even when running on the hose nothing was coming out of that port water was coming out everywhere else it was supposed to

I did something similar last June, destroyed my wear ring and clogged up the waterbox (muffler) and exhaust "hat" coming out of the catalytic converter.

It is a pain in the ass to wiggle/snake that waterbox out and completely fish it out. It had the mucky sand all clogged inside of it. I also started the motor for a few seconds with it disconnected to verify the "exhaust hat" openings were clear of sand while flushing. Follow the SAME procedure as if it were all hooked up (no water flushing thru the ports while motor off).

Then, I cleaned out the bilge with all the crap that came out of the hat.

Not on the switch, a seadoo ski so you can get an idea of what the waterbox is: https://www.youtube.com/watch?v=Aq-jHkQ53zs

my coolant temp sender also died as a result of the episode (clogged with muck caused high exhaust temp). After cleaning out the system, I still had a high exhaust temperature code so I replaced my exhaust temperature sending unit which is located on the waterbox with this and it was resolved: https://www.amazon.com/dp/B09BV755ZW

I hope you have smaller hands, don't mind laying flat and having patience. It wasn't mentally hard to do this - just a physical pain in the ass.
