Outboard not peeing

[Birdguy]

Well, new thermostat and salt away and still not peeing. We did take it apart after running it and the thermostat was getting water. Starting to get a bit more frustrating for sure. Thanks again for all the ideas. Will update when we get it!!

Did you ensure the impeller was oriented in the proper direction when you changed it ?

Might want to check the water path I've had the fitting get corroded and pluged.

Well only three other options.  The impeller is in backwards, the pin that links the rotating shaft to the impeller is missing or not installed correctly, and lastly the pick up tube from the lower unit is not getting pushed into the proper down tube on the engine.

Wired incorrectly?

I would go back to impeller . I had one go bad on my Evinrude 90 and replaced it with the knock off new impeller and still had no water peeing . I went back and bought the actual Evinrude one and worked like a champ last 5 years. Not much there to produce water obviously,  I'd make sure impeller is the right one and installed properly first before moving on again to other causes .

I have had a 40hp that was difficult to get to pee on muffs, and had to be submerged.  Replaced an impeller, pump, and thermostat on it and could not get it to pee ever on muffs.  Put it in a stock tank and she purred like a kitten and pissed like an old man

This is actually pretty common.

Check the piss tube, right at the opening. Leaf cutter bee's and Mud dabbers love to plug the piss tube on my 150.

So a pretty weak stream but what seems like every hour or so?

We will check the impeller again, it is the same size and make as the one we took out (bought at a Suzuki dealer). Yes, the pin is in and lined up correctly. I think with the pin it can only go in one way as the channel for the pin does not go all the way through so it really only goes one way. We started with pulling the plug out of the out port and ensuring things were clear as far as we could push the weed eater string in. Same for the pick up when we had the lower end off. If we had something plug or break it is in above the pick up in the mid section of the motor where we cannot see. We are considering dragging it to a lake to see if submersion changes things. It is just another annoying punch in the face this summer. At some point it has to get better.

you know that the vanes have to be going in the right direction or it will not pump water.

It may have high speed pickups that aren’t getting covered by the muffs. You can try putting duct tape over the those intake screens and see what happens. I have a Yamaha F250 that won’t pee on the hose with muffs even with the high speed pickups covered but it will be like a champ if submerged.

Are you running it long enough?  Not all motors will pee right away some need to warm up before they will start peeing.

Yep, wife and I went out to swim on CDA Lake last week and the duabers had plugged our pee exit tube.
Dug it out with a wire, and a small grub larva popped out of the tube with the mud. Peeing good as new after finding issue.

Just don't run too long with no pee, you'll burn up impeller.
