Just a suggestion but pull your add until you get it resolved. People will be scared off if you have to make excuses. You're not just turning them down you're losing them for good. Good Luck.

  1. I have seen posts on here confirming some boats won't pee on the hose, only in the water. Maybe try it?
  2. To test the "thermostat opening" theory, pull out the thermostat. See what happens.
  3. If still not peeing after trying the above, could you pour something down the hose to try to clear the blockage? Salt-Away? Vinegar?

Good luck! Keep us updated when you finally solve it.

Yeah, I'll try anything. I wish I could run it long enough to heat up. I don't know how long it takes running at idle before the block heats up and risks damage without proper cooling. Do you? Maybe a few minutes at idle?

I didn't think to test it WITH the thermostat housing mounted in place but WITHOUT the thermostat actually installed. That'll at least let me eliminate the thermostat if it's bad (although I could manually push in the thermostat). But as a post mentioned on another forum, water will take the path of least resistance and so without the thermostat in place, water would normally flow out through the bleed hole but at the cost of not fully cooling the block. I'll try this idea. Thanks!

Did I miss if the OP said if it is overheating or not?

If it's not overheating and the water is coming out the exhaust, then it's obviously a clog. Run it. I don't think I've owned an outboard that didn't get clogged at least once. Follow the system all the way back.

If it's overheating, that's another issue -- but I'll bet it isn't.

Ok. So...here's what I do on a regular basis. I ALWAYS observe the water thats pouring onto the ground around the muffs with the engine off. Basicly ...all of it. When you crank and start it, a good portion of the water should be observed going INTO the engine water inlets. That's the water pump doing it's job. Less water on the ground. It would take at least 45 seconds or so for the engine to get warm/hot for you to start seriously worrying about heat damage to the motor. Touch it frequently !!! If water is going in, it should be coming out. where??? Propellor !!
I look for these indications on every motor I run. Automaticly, everytime.
In my neck of the woods, the tell-tale hose or the nipple often gets plugged by "cutter bees". Patience, air and sometimes a very small torch can help break up the "bees". Dont melt anything you dont want to!!!!!

have you tried sucking on the tell tale? If it’s clogged you’ll know right away. If it’s weak pump, you should be able to suck water through it.

Oddly enough, this same thing happened to me this weekend. Yamaha F150 wouldn’t piss after new water pump. Motor only has 200hr. Tried muffs, and a tub (I thought was full enough). Long story short, after taking apart the water pump 3 times to double check my work, I had someone hold the sides of a plastic bin so that half of the outboard was submerged. Primed right up.

Yeah I think I'm just gonna go the old-fashioned route of thin wire and an air hose. But that could certainly make for a good YouTube video. Lol

Ok here is the funny/not so funny irony of your post. I began thinking the same thing as I tried a full tub and still no peeing .Like you, I took the lower unit off for like the 5th time .But then I thought "wait...a couple holes were not submerged, thus air, thus no pressure....". So next step is to put the prop in a deeper tub. But low and behold, magically, I can't get the F#@%$&# lower unit back on! Like what the actual ?? It was everything I could do not to send the prop max G's into concrete.

And that is where it stands now. If I am calm tomorrow, I will try try again .

Did you remove and clean your strainer screen? I have seen them totally clogged full of weeds and debri.

"I can't get the F#@%$&# lower unit back on!"

Well, now that you have it off connect a hose to the water pickup tube and secure with 2 hose clamps. Tight but not too tight that it'll deform the tube. Turn on the water and see if it comes out the tattlletale. If so start the motor and let it run for a while to see if the tattletale gets clogged as the block is flushed of deposits.

Then check the screens on the lower unit.

Shift the control arm into Forward, just when it engages. Take a pliers and shift the lower unit into Forward -just when it engages. Then re-assemble. Verify shifting ranges with engine off and shifting FWD, N, Rev and spinning the prop to verify gearing. Getting a clean N from FWD and REV means it's good. If it's a little off adjust the shift cable. If it's a lot off shift into FWD, drop the LU and repeat.

Rent a boat for the showings.

Go half on coffee and alcohol until the boat is finished.

Resume posting in lower case and normal characters.

Is it ok to run the motor with drive shaft and foot removed with a water hose on the water tube in foot? I have a little smoker that needs this done for troubleshooting

Could there be a blockage down where the prop is and if so, can that lower unit even be serviced? What about from the impeller up through the housing? Is that hose accessible without taking the whole damn thing apart? Anything else semi-simple to check?

This one f*****g problem is going to cost me from selling the boat. That and the Garmin decided to quit working (backlight out).
somerimes my motor does The same but when I put it under load it’s pees. Have you tried applying throttle and see if it pees under load?
