Tell-tale obstructed?

Just started my 81 Johnson 115 last night and fired up just fine. One problem, no stream from the tell-tale. The water pump, housing and all seals were replaced and, yes, I rotated the drive shaft clockwise while pushing on the cup liner and housing.<br /><br />There is water pushing out the center of the prop while running with the exhaust. So having said that here are a few questions:<br /><br />1. Does the water coming out the exhaust (It's a pretty good flow) while running mean that there is circulation through the engine? <br /><br />2. Could it be that just the **** hole, fitting or line is stopped up? <br /><br />3. Anything (hoses, a fitting, etc...) that I can remove for a second to check for proper water flow at the powerhead?<br /><br />4. Does the water flowing from the tell-tale exit the engine before the thermostat or after and could that have anything to do with it?<br /><br />The water pump replacement was so routine and seemed to only go on one way. I used all O-rings, lubricants and hardware supplied with OMC's kit and followed the Clymer's manual to the letter. I've got to believe that it is working properly. Thanks for any help.

Re: Tell-tale obstructed?

Hey mworthen,<br />Did you allow the motor to warm up before shutting her down? Once the thermostat is open you should have a stream from the tell tale. If you don't, a blast of compressed air back through the tell tale will often clear the obstruction. Are you sure you got the pipe from the pump to the powerhead properly seated in the powerhead? Did you have a stream from the tell tale before you replaced the impeller? <br />Backlash

So the telltale will not function until the thermostat opens?

Sorry to say, I'm not sure on your '81 Johnny. Many motors show the stream from the tell tale upon startup...others require the stat to be open. What did it do before the water pump job?<br />Backlash

Never ran it before the water pump job. Brand new (to me) boat. I've got to believe that if I'm getting water discharge out of my exhaust while running that I have circulation? Is there a hose on a Johnson that I can pull to check flow? Thanks.

Re: Tell-tale obstructed?

How long have you run the motor? If you can warm it up and still rest your finger on the cylinder head or exhaust plate for 5 seconds or so, you're cooling. Could just be some crud in the tell-tale line or a blockage in the fitting from the block. Try a puff of compressed air or run a small wire in the line, and restart.

That motor should pee all the time, even cold. I've had Johnsons clog that hole, I even remember pulling and outdrive only to find an ok impeller, only to have the peehole clogged. You should be able to remove the hose inside the case to see if it pees. usually the piece on the case clogs.

Thanks everyone for the help. The telltale was clogged at the fitting. My Johnson now pees freely, wait a minute, that doesn't sound right. :D
