Outboard not peeing

[Birdguy]

Good evening, we have a Suzuki 140horse, we pulled it out of storage to get it ready for use. When we fired up the big motor there was no water coming out. We turned it off, took it apart got a new impeller replaced the impeller (though the old one looked good) and put it back together and fired it up still no water. We dropped the low unit and put the muffs just on the lower unit and when I tuned the shaft it moved water into out the tube that connects to the water outlet. We blew through the tub and water an air come out but it is up inside the housing, same result both ends. It is almost like there is a hole in the system. Anyone ever had or heard of such thing? By no means am I a mechanic and feel we have may have reached the end of our comfort level taking things apart. While in the water all this area would fill with water but I do not expect it to push water through any better than the muffs. Any thoughts or ideas before taking it in?

Run a wire down the hole and see if it’s plugged. I’ve had that happen before. The water pressure is not enough to blow it out. It’s worth a try.

Try a pipe cleaner
I keep one on my kill switch cord

A blast or two from an air compressor might knock it out if it is a plugged tube.

Keep em coming! We tried the pipe cleaner, we used weed whacker string and got about 18 inches up from the bottom and about only 8 inches from the top side(seems we hit a corner). The air came out but not through the other end.
   We are going to buy some "salt away" tomorrow as we hear that may work.

Most of the big outboards have a plug next to the thermostat housing. If you remove it does water come out?

if the hose from the block to the cowling is clear, then disconnect the hose from the block and run the weedwacker line into the block from that port.  If you are trying the air compressor, try to get water into the system from the top port where the hose connects, then hit it with the air compressor.

Thanks guys, we will try these in the morning! I sure appreciate the ideas!! We are learning and are thankful for this resource.

I've had used air to clear it most times I usually fire it up and then shoot air in it usually starts to pee right away

I have a 70's johnson 15hp that was never even designed to have the pee spout. I don't know the year of your engine, but if it's real old it might not be designed to pee.

I hate to ask, but what does your oil look like? If it is milky or if it is high, that is bad, but easy to check.

Like others have said though, it sounds like a clog. Some are hard to get out, but most get out by shooting highly compressed air into the outlet.

Whats the serial number on the engine so we can look up a parts diagram of the cooling system?

[Kola16]

Also, if it won't pee on the hose then it definitely won't pee in the water. How does it run? Is it still cooling? Does it start to sputter after running it for a while? If it is running fine without sputtering or excessive smoke out of the exhaust, then it is getting cooled, which is good.

Hey Birdguy don't you live close to me? Shoot me a PM before you take it in if you're interested. Free of course!

I have the same motor. In 2019 it wouldn't pee but didn't overheat. Finally had a Suzuki tech look at it. Turns out the thermostat was stuck open. Apparently that kept it from warming up all the way.

blast of compressor air, try running some saltaway into the motor and let it sit.  Wire up the pee hole a foot or two also works on my kicker.
