1999 90hp Johnson Not Peeing

[LGM30Glauncher]

I bought this motor new and this is the first time I've had any trouble with it. It's a 1999 90hp Johnson, 2-cycle. I'm getting ready to sell it and I wanted to show potential buyers that it works. I bought a pair of muffs, placed them over the water intakes, started the water flowing and started it up. It started fine, but no pee. Then I read through the "micro" manual and it said to have the motor at a good tilt. So, I tilted it as if it was on the lake, but still nothing.<br /><br />My brother said with the muffs, it should pee even without running. Is this correct?<br /><br />However, it's cold here (45 degrees). Is the T-stat not letting the water pass until it's hot enough? If so, how long should I wait (I get nervous with no pee). So far, I haven't waited long enough for any idiot lights to come on and I really don't want to.<br /><br />I've looked through a lot of these messages concerning the pee problem, and at this point all I want to do is get a good plan together of what to check, in what order.<br /><br />My list, from what I've read so far:<br /><br />1. Check for clogged intakes (I already did this, they look great).<br />2. Check for a plugged pee hole by cleaning it out with a wire (paper clip).<br />3. Check to make sure the pee hose is still hooked up.<br />4. Check the T-stat.<br />5. Check the impeller.<br />6. Just plain screwed.<br /><br />Thanks, ahead of time.

Time to replace the impeller... Case closed... <br /><br />It does not "pee" without the motor running on the muffs...<br /><br />The impeller should be replaced at least every other year, so if you've never replaced it before, then you're over due for a new one...

So you're saying this motor doesn't have a T-stat and/or it is not a factor - correct?

The pressure relief valves stick on this engine, and it has 2 thermostats. I would start engine on muffs, give the tattle tale a shot of air pressure, increase rpms to about 2500 rpms for 10 seconds. Im guessing,because you did not give model number. Engine could be a 60 or 90 degree engine.

Engine model number is J90PLEE. In this situation, what specifically should I know about the 60 and 90 degree engines?<br /><br />Also, I finally got a hold of the dealer. He said the same thing you people did (that's good to hear - a little trust builder).<br /><br />The boat is stored outside. I will try it again when the temperature climbs higher than 27 (brrrr).<br /><br />The dealer also said that the impeller is usually replaced every other year - I had no idea. I've had several other smaller motors for years and I've never replace impellers on them or had any trouble. Thanks for all the help.
