I just purchased a center console with a 1993 Johnson 140 V4 Oceanrunner and I'm somewhat confused about where the tell-tale is and how much water should be coming out of it.

Model # VJ140TXETF
25" Shaft
90 LV (I think)
VR02

I've attached a picture showing two ports under the engine cover. Is #1 the tell-tale? It's located directly under the engine cover in the center. What is #2? It's located on the starboard side in the back corner. I have no water coming out of either but the other day when running in the driveway I did get some steam coming out of #1. As soon as I bought it I replaced the impeller and when I took it out running yesterday (for the first time) I forgot to check for the tell-tale (stupid me but I was having fun). I can touch the heads and hold my hand on them without blistering. How much water should be coming out of the tell-tale?

When run with muffs there seems to be a lot of water coming out all over the place around the lower unit and where it connects to the midsection. Based on posts I have read, this seems normal and much to my surprise when I replaced the impeller it doesn't seem like the impeller/water tube connection is air tight and would leak water easily when under pressure like that. Is this normal?

After turning off the ear muffs as the water is draining it takes some time to all drain back out and the water coming out is very warm so I assume it's made it up to the heads.

In the bottom picture is a hose which is not connected to anything and I can't for the life of my find where it goes on the motor? I've only included this since it might be related to the tell-tale. What does this hose go to?

Can I back flush the tell-tale with my garden hose just to see if water comes out the bottom (after you tell me which one it is)? I ran a hanger up in to #1 and nothing seemed to be clogging it at least as far as I could get into it.

And you should know when running at about 4200 rpm or higher the warning buzzer goes off as a constant buzzer and then when I slow down it will shut off. If I run it at 4100 rpm no warning but once I started creeping up higher I got it. I have not run through eliminating the cause of the buzzer and there are no indicator lights in the dash telling which warning is going off. If it is related to overheating, it seems odd that I could run all day at 4100-4200 rpm all day with no problem but then anything higher gives me the warning within a few seconds.

This is getting lengthy so I'll stop to spare you. If you need more information please ask. I really appreciate this board and all the help it’s given me from reading all these posts.

Thanks

Mudd

Pee hole is on the right in the top picture.
Fun or no fun if you get a buzzer that goes away when you slow down then you have a cooling problem. How about thermostats ?? is the impeller in correctly ??

Re: 1993 140 Cooling System Questions

I feel pretty certain the impeller is in correctly. I used the SELOC outboard repair manual as a reference and I paid close attention to detail (made sure it was turned the correct way, made sure the key stayed in place, made sure everything lined up correctly when I bolted the lower unit back on). I have not checked/tested the thermostats yet and they were replaced August 2006 but that doesn't mean they aren't bad. I'll add that to my list to test and also test the temperature switch.

As a test, can I remove the thermostats and just leave the open hole and start the motor with the ear muffs on? If water comes out isn't that a pretty good indication that I'm getting flow to the heads? Even so, my tell-tale is doing nothing so something is going on.

The large hose in the second picture along with the smaller hose attached to the same spot go to #2 so it would appear the tell-tale may be bypassed unless of course the small hose is all that's needed? Would it hurt anything to blow compressed air back into the small hose?

Re: 1993 140 Cooling System Questions

You must be getting some cooling as the motor is still running. If no water was getting through then it would have self destructed by now. Was and or is it used in salt water ?? if so it could have a build up in the system.

Re: 1993 140 Cooling System Questions

Weed whacker nylon line is good for checking and clearing the pee hole. If the motor has not been run for some time then you may have some "insect blockage" in ther. Just like getting the spider webs in the BBQ jets over the winter.

Re: 1993 140 Cooling System Questions

Yes it has been run in salt water. Now I understand the post which mention using weed whacker cord. Before I couldn't understand how it would fit in that big exhaust port I thought was the tell-tale. I'll try that tomorrow night. In my pictures do you have any idea where the larger hose should connect on the motor? It is also connected on the end to the same pee hole.

What about the port I marked as #1? What is that for? Engine exhaust as well?

Thanks

Re: 1993 140 Cooling System Questions

The motor is now peeing and the problem was the plastic connector on the end of the hose which leads outside of the motor was clogged.

However, I now know it was getting the proper cooling so the alarm must be something else. The SELOC manual states a constant alarm is either overheating or insufficient fuel at high RPMs which makes sense since the alarm only happens at high RPMs. Any thoughts or suggestions on this? I guess I'll get it out and get the alarm to trigger and then unplug the high temperature sensor to be 100% sure it's not that sending the alarm.

I still wonder what this other hose is for. It's not connect to anything. Anyone know? I have posted more pics of it here along with my motor which doesn't show an obvious disconnect.

Thanks for you help.
