cooling water flow issue?

[bflee1]

I have a 1987 Evinrude 9.9 that I think has an issue bjt I am not sure.
It drips water out the tell tale unless at high rpms, then a stream forms.
The thermostat opens and just a spray comes out the port.
It has water coming out the lower front end. I am trying to load a picture but dont know if I got it.
The black rod shows where water is coming out if it loaded.
Funny thing is it never gets hot. I ran 10 miles on the river a couple weeks ago and it never got hot enough that I could not put my hand on it and leave it there. I hope someone who has one or works on them can help me. I have not had this motor but a couple months but this just doesnt seem right to me.

Fist off, your motor needs to be deeper in that tub. Your impeller has to be under water for it to work properly, or you will ruin the impeller. The water level should be at your straw when starting and flushing motor. The only time it should be below that is when moving forward fast and cavitation plate is at to of water, but water is being forced into water pump then from forward motion.

It is not unusual for extra water from water pump to run out of these other areas. When you use a flush attachment to flush your motor, forced water always runs out of these areas, but put your motor deeper in that tub to run it, for flushing, or testing.

It is possible something has formed a home in your pee tube, try pushing a monofilament (thick as will fit) up the pee tube WHILE MOTOR IS RUNNING, YES, DEEPER IN YOUR TUB.

If motor won't go down more, put tub on a couple blocks of wood to raise it, or raise the tongue of trailer higher, to lower motor more.

Good luck.

It does the same in the water deeper solarman. I have taken the pee hole tubing off and poked it all out. It just isnt getting any pressure. I thought it was more originally, but its not running hot so I guess I am getting some.

Ok. I'll say this one more time. Raise the water level up above that black pin stripe decal where the lower unit separates. This is the level of your impeller. It is already possible that your impeller is damaged some now, just from starting the motor with the water level in the pic. If the impeller runs dry for a couple seconds, it is very possible for it to fragment from being dry, sending fragments throughout the cooling system. It is not self lubricating, it has to be wet from the very first movement.

I won't say anymore, but good luck.

It was like that on the boat in the river also when it was deeper I dont think that is my issue but I will take your advice and put something else under the barrel to keep from causing further damage. I actually had the water up to the top til I ran it in gear. I appreciate you sharing your knowledge with me, I thought the impeller was a lttle lower.

The tell tale tells you the pump is sending water. It is possible there is a blockage (corrosion or piece of debris lodged in a pas-sage) causing limited flow, a missing or stuck open thermostat (may lower the pressure in pas-sages by not closing down partially?), or a damaged impeller, or damaged impeller housing? If running in shadow waters, I have heard of blockages caused by small shells and mud.

Many things affect flow, it isn't easy to know exactly what. On my motors exhaust grommets burned out, allowing exhaust gases to push water out of my water pump, so at idle I had a great pee stream and motors didn't overheat. But at 2k RPMs both of my motors pee streams sputtered and turned to steam. Found out after weeks of searching that the previous owner's Mech put heat shields in backwards allowing the hot exhaust gases to burn out those two $3 grommets. Once corrected, motors were fine.

On your motor, I would check thermostat first, to see if stuck open, or if trash is there. if trash, what does it look like? If you can identify, it may tell you your next step. While thermostat is out (motor off) try putting a garden hose with good pressure where thermostat was and back-flushing the system (if your container is empty and clean, any trash coming out might tell a story?).

Good luck. Post back if questions.

Thanks.. I will remove the tstat and go from what I find there.

Also, if thermostat, or back flushing (pee tube, and thermostat), see if black little pieces of rubber, that might indicate the impeller, or some grommet is damaged.

No need to post back till you do this, will wait to see if anything shows up. Good luck.
