New impeller, still no stream

9 posts in this topic

I've got a 7.5 HP Merc. Not sure of year,Mid 80's I think. Serial #7208663 for what its worth.

After sitting for 6 years or so, it fired right up, but no water from pee hole. I replaced the impeller, but still no stream. I can push high pressure water through the flush hole and get some to exit the pee hole.

Is there a thermostat on these things that may be stuck?

This is my last resort before taking it in.

Thanks for any info

Jeff

Jeff,

Not sure if this helps much, but my mid 90's 9.9 has a thermostat on it and it doesn't pee until it starts to heat up a bit.

Thanks for the reply Paul. How long does it take to start pumping? I ran it for 2-3 minutes and still nothing. I'm a bit nervous to run it too long.

Depending on the water temp and the load.....3-4 minutes.

Is it installed properly? If it's put on backwards it will not turn correctly...also it has a little key that needs to be installed along with it.

I know these are stupid questions, but had to ask.

Yep, it's in right and the little key is in too. I guess I'll try it again tommorow and let it go a little longer.

Thanks again

Questions... Could the pee hole be clogged? Is the pee hole the smallest hole in the cooling system? I don't know.

But, my Johnson was not 'peeing' like it should, so I took the pee hole apart and found a small pebble where the water comes out plugging the output. On mine it just unscrews from the cowling.

(I hope that makes sense....my post sounds like I should see a urologist)!

There should be a small hose running from the block to the cowl for the pee hole. Disconnect that and see if water sprays out of that. I had the end of mine plug with sediment once and I had just replace my impeller too, kinda of an "AH SHOOT" feeling until I found the plugged hole.

Thanks for all the suggestions.

Turns out, when I pulled the lower unit, the tube up to the powerhead came with. When I put things back up, the tube did'nt go back in the hole.

Things are fine now.

Man, I just cannot stop laughing at this...sorry for this reply but if you read your reply with a little humor it does not look good....talking about pee, holes, and Johnsons...grin.gif

..then you say yours "unscrews".... laugh.gif

Anyway I am glad you found the problem, the 3 things are a little tough to line up sometimes (water tube, driveshaft, and shift rod). laugh.gif

      Thanks. So it hasn't changed much then. Still might go give it a whirl!

      If you haven't read it yet, a couple of slobs are about to ruin it for the rest of us. Pick up your garbage and respect private property. The land owners who allow access to the lower sucker river are about to shut it down because they are so fed up with it. http://minnesotasteelheader.blogspot.com

      With the wind being fairly strong today I opted to hit the back waters of Little Rock. Have done goid there in yrs past.... so I figured it would be worth a shot. Finding crappies was pretty easy, they were holding tight to the brush and downed trees. Finding crappies over 8inches was tough...lol.  I don't think I broke 9inches. But did manage one big carp. Guessing right around 30in, pulled me and the yak all over the lake before I got it boat side

      Hit the one down by Watkins a couple times this winter. There were a lot of people that fished it this last winter. Got gills and crappies of all different sizes. If your looking for keeper size fish, other area lakes will provide better numbers. Haven't been on the other one of  in a few yrs. There were good numbers of 6-7in sunfish if I remember right.

      Looking to get a different depth finder for my boat, one with GPS and side imaging. I have $650 to spend, and have found a new Helix 7 SI and a used 998c SI HD with about 800 hours on it.  They both are $600.  Which one would you get and why?   Thanks!
