Water tube grommmet

[Damifudo]

When I changed the water pump with a new kit. I changed all the old o rings and gaskets. Reading the instrustions they said to make sure you install the new water tube grommet ? hmmmmm never saw an old water tube grommet ? Where does it go? so I installed it in the water tube. Everytime I tried to install the lower unit the grommet folded over inside the tube. I greesed it still same problem. I removed it form the water pump and tried, realized it has to be pushed almost to the bottom of the tube to fit properly and not fold over when I install the lower unit. Once the unit is installed there is no way of knowing if the grommet is postioned properly I assume you have to just test water flow and have some faith?

Now I am also worried what happened to the old grommet that was not there? Is it up inside the engine someplace? If so how do you know and what do you do about it? I assume the water tell tale will tell the story if everything is ok?

I am tying to gain experience from asking question here before I make the dumb mistakes.

Re: Water tube grommmet

Normal installation is that you put the grommet on the water pump housing, grease it and the end of the water tube and very carefully slide it together while watching as best you can for alignment until you have to fart with the shift linkage and from that point on you kind of ignore the grommet cause the shift linkage won't go together. I am saying this with tongue in cheek but it is kind of the way it goes some time. Normally it all works out but I have had to re-drop the leg a couple of times to get the tube in the grommet. The water tube fits inside the grommet in the end. Best of luck. Rick.

I was kind of hoping that the donation in the church plate helped it all to line up ok. I was saying my prayes, I hope the old one is not deep inside the engine some place.

Re: Water tube grommmet

the grommet goes on the water pump housing where the water tube is inserted. There is a second grommet (depending on the motor????????) in the exhaust housing.

I think I have it all installed in the right place as long as it didnt mess up in the tube. I put it in the water pump outlet tube and pushed it down toward the base of the tube.

Re: Water tube grommmet

Sorry I forgot your comment about where the original might be. I would guess it was omitted by a former repair person. I cannot imagine it going up the water tube or pushed back into the water pump housing. My money is that you need not worry but you could put a little more in the plate just to be sure. Rick.

Re: Water tube grommmet

well I got her fired up tonight and she ran and threw a pretty strong stream out the tell tail. I let her idle for a few minutes and check the heads warm to the touch is all and the tell tail got warm not hot. What I did notice was alot of water flowing out around where the lower units connects to the middle unit. I assume thats not a good thing to see that much water spraying out where the two parts come together. I assume the grommet once again is twisted up inside the water tube. Time to drop the lower unit again and check. Uggg

Re: Water tube grommmet

I will drop the lower unit today. Is there anything eles I should be looking for about getting this grommet install properly? I had great water pressure it is just I had water spraying out around the seam where the lower unit bolts up to the middle unit? I assume a grommet not seated properly or one that truned when installing the lower unit. This is my first pump change on a Johnson the Mercs seemed much easier to get the water tube together.

Re: Water tube grommmet

Are you on the muffs ??? Can you post a photo or even a video of the issue you have. You may not actually have an issue, mine comes out all over the place at the joint. I just noticed as well that we have no idea what motor you are working on.

Re: Water tube grommmet

oh i am sorry I am working on a Johnson 150 HP 150JSLEDB and yes I am on the muffs. I will post a picture if I can the next time I get it run again. It kind of sprays out around the joiint around the lower unit. I will try to get some video.

My other question is should the alarm on the Unit sound when your turn the ignition switch on? The lights come on and then go out. I just add the OMC Tach that has engine lights built in but the Alarm never sounded. Whats the best way of testing to make sure the alarm works?

Re: Water tube grommmet

I don't know about the 150 but on all the smaller engines I work on that's normal for water to come out of that joint on the muffs as it's just part of the water return going out the exhaust. There's no gasket there (again, on smaller engines) thus I believe you're fine. Unless there's something unique with the 150 and if so maybe someone will step forward.

And Kennyfam, Where the heck are you? In Korea or Fla? Or somewhere in between?

Re: Water tube grommmet

So can someone say if its normal to have water spaying out of the joint between the lower and middle unit on a Johnson 150 on muffs. I dont have pictures today because its raining but I did have a good strong tell tale. I was thinking this week when the weather is better to drop it in the water and see how things work. This is a new engine to me. I am trying to get to know it better and whats normal and what needs attention. This engine has been sitting and not used much for 5 years and been sitting 2 years not used at all.

I am going to see how it runs before rebuilding the carbs by checking each head with a temp gun and a thermal imaging camera. I will try to post pictures of that it should be interesting.

Re: Water tube grommmet

The joint between the LU and the midsection isn't sealed and water comes out normally, although some people use sealer there BC the water bothers them. Water should be coming out of all the little drain holes as well. Not to worry.
