Okay, 1977 25hp evinrude. dropped the LU, impeller looks okay, starts fine, running in a barrell but I did not see any stream coming out the pee hole. I do see some water spraying out of the back of the shaft (the 2 holes higher up on the back of shaft?), but no stream out the pee hole. I cleared the line and can blow through it fine, help me out please!

remove the line, and take something like a paper clip, an clean out the fitting. you have a blockage somewhere. does 77 25 have a tale tell? Yep!

Another thing you can try is to leave the line off where it connects to the pee hole and run it. That way you know if your getting water through the line at all.

Go Dawgs!

I have run a wire through the hose, it is clear...I will try running it without the hose connected though, just to see. I can feel air coming out of the pee hole...just no water.



What are the holes in the back upper shaft where i see water spraying out?

Re: ugh, cant figure out why no pee?!?!?!?

I think you are talking where the exhaust comes out, not sure.

You might be in the same boat I was in. Right before a big fishing trip last month my engine stopped pumping water out the pee hole.

I must have dropped the lower 20 times and reinstalled it before I got it working. First off, the impeller seemed fine. I think it was, but I changed it anyways. I ended up finding 2 problems.

First, the water tube broke off in the grommet at the base of the block. That meant I wasnt getting a good seal at the top of the water tube. I ended up having to pull the head to access that grommet. Its not as hard as it looks doing that.

Second, I dropped the lower so many times I ruined the bottom grommet.

You want those 2 grommets tight if you are to get any water through the block. What I noticed was when I ran the thing I was getting no water through the block, but water was pouring out of a few holes in the midsection indicating it was pumping.

One way you can ensure the pump is pumping is by taking the lower unit, driveshaft, tube and all off. Duct tape a drill to the end of the driveshaft real good. Submerge the lower as deep as it would normally run and turn the drill on. It should pump water out the pump.

Once you know that the pump is working, you are basically left with a plumbing problem somewhere to diagnose.

Good luck. Oh, and for the record my model was a Johnson 28 SPL from 1986 with the old style exhaust. Probably similar to yours.

Man, that might be it, as I do see water coming out of some holes in the midsection of the shaft.

Is there a website where I can see how to pull the powerhead off? do I need to buy a new water tube? or just get the grommwt out and put back on?

I can use any and all help.

I also just read that the water tube should not come off with the lower unit...mine did come off with the Lower unit when I took it down, maybe I should drop the lower again, install the water pipe first then put the LU back on???

the tube should not come down,it should have a collar that would prevent it from sliding out ,that may be causing a stream loss at the top of the tube

haha, I got it figured out, since the water tube was coming out with the lower unit it wasnt seating properly when I put the LU back in.

I took the LU down, took the water tube off, installed the tube up in the shaft, then reinstalled the LU...fired her up and it pee's like brand new.

Thanks for the help guys!

Its a great feeling when you see that water come out of the indicator for the first time. I think I did a jig in the middle of the street. Glad to hear it worked out for you.

Re: ugh, cant figure out why no pee?!?!?!?

nguoi, you need to start a new post of your own. You'll get more responses. If you haven't dropped the lower unit then you also haven't replaced the impeller, which is the likely cause of your cooling problem.
