Long winded so bear with me .
Went out today to try and catch some Walleye and try out my buddies' new ( to him ) boat . He bought it last fall and has never owned a boat , I have . I was giving him the run down on things to look for and things to do, etc . Was running on the big motor and explained, " Make sure you see water peeing out of both motors every time you start them."
All was going well , so I said, "Let's fire up the kicker 2015 Yamaha 9.9 and check it ." I was running it and knew I saw water peeing out . Awile later, kicker shut off . I fired it back up and noticed instantly it wasn't peeing . Pulled the cover, and it was warming.  Motored over to the dock and started pulling hoses and blowing in them  when air went through what I could reach in the water I decided to pull the boat so I can check out the screen on the bottom etc on land . Pulled the screens and found chunks of dried, weathered rubber behind the screens and in the hole that goes up to the head . Pulled all that out and blew through the fresh water flush connection  . Heard and felt air coming out where the screens are . Dipped the boat in the water , started it , no peeing , came home . On to the question is there some rubber gasket down in that area around the screens ?  How hard is it to get inside the lower unit ? Any other ideas ?

The impeller is made out of rubber. Maybe it’s shredded and you need a new one. I’d pull the lower unit and check.

That would be my guess.  Pretty easy to pull the lower unit and check it out.

Remove 4 bolts and pull it off.  That easy.  Try YouTube for how-to

I recently replaced water pump impellers on both my 90 & 9.9 after watching a Youtube video, it was easy and was done with both in under 2 hours.

Yep sounds like impeller, I’ve had the same thing happen, seen rubber pieces behind the screen.

All that

The more I research the more I'm thinking it's the impeller.  And should be an easy fix . Told him we will.tear it apart Friday , find the damage and get parts coming.  Just glad we didn't smoke the motor.

I now keep a paper clip in the boat.  About every other year the pee hole gets clogged with a spider or something.  I straighten out the clip and poke the hole while running and boom there it is.  Sometimes there's a weak stream.  Same fix every time.

Once I did have to put a new impeller in.  Easy fix on a small outboard.  Well, it did take me two times to get it installed correctly.

Cheap and easy, replace it before it’s a problem. Annual or bi annual maintenance

Same, have to check every year for bugs that crawl in and plug up the hole.

I would replace the impeller and the thermostat. It will most likely end your problem.  I would most definitely do them both.

THIS.

Its surprising how quick an impeller can go bad (especially if ran out of water)

Get the parts on hand before you disassemble.  You'll want to replace it no matter what while you're in there, so might as well do it all at once.
