Hi.

Got a 9.9 Johnson with no tell tail. Took off lower unit and inspected impeller.. is fine. Then hooked up drill and put it in bucket to make sure the pump was working. Looks like it was working fine. Made sure no clogs in tail hose. It’s fine. I can even put my mouth on the hose, blow, and air goes out though and down to the water inlet. When running, some exhaust does come out of tell tail

Im at a loss. Haven’t had the boat in the water in 3 months but didn’t have an issue then. Only thing I can think of is I don’t have it running in deep enough water when testing but it’s in a bucket with water completely covering intake.

Ideas?

Water has to be above the pump itself. Is the water tube lined up in the pump housing.

So I’ve done it in the bucket and with the muffs. I feel like with the muffs it worked before but it’s not now.

And I believe it’s lined up. It was working fine in late August, then it sat and then it’s not working now. I opened up lower unit and believe I assembled everything back fine.
 
Thanks. I’ve used muffs before and no issue. Now it seems not to work.

I stuck it i a. Whole trashcan now and it works. However it looks very oily in the water now. I am wondering if I messed up a seal in the process or if it’s just from the exhaust of the oil/gas mix
 
That is 100 to 1 motor. I run synthetic Amsoil in all mine, the design of the basic Powerhead hasn't changed Since the new generation 9.9 / 15's. I would never run 100 to 1 except with Amsoil. I warranty all my repairs for 1 year. Have to play safe.
 
You can't always trust the pee holes, they plug with crap, clean them first before you dig into the water pump.
 
That is NOT a 100-1 motor. The 100-1 fuel mix was for mid to late 80s motors and was changed back to 50-1 pretty quickly. They changed it back because the motors were rusting while they in storage. This was because there was not enough oil to coat the parts during extended storage and things were rusting and being destroyed. 50-1 is the correct fuel mix for your motor.

I have a '79 Evinrude 9.9. Outside of some differences in the exhaust tube it's pretty much the same engine as yours. FlyingScott is right, run it at 50:1

I use the Evinrude Premium 2-stroke oil available at Wal-Mart. It's $20/gallon and that lasts me a long time in this little motor. This oil burns super clean and I hardly have any smoke even when I'm trolling.

Quite a bit different between a 79 motor and a 94. There was a design change in 93 on the 9.9 15 hp block the 94 is a 15 cid block where the 79 is a 13 cid
 
????----So the newer motor has bigger pistons and different shape intake ports.----Same crankshaft , rods and bearings !!!!
 
The 100:1 was a marketing / board room ploy to retain market share.-----Many folks simply do not know much about how oil " works " inside a 2 stroke!!-----Folks were walking out of OMC showrooms because they believe 100:1 motors must be a better motor !
 
I still run my 15's at 100 to 1 but only on Amsoil 100 to 1 pre mix or Saber pre mix. The 93 and up, I don't have an example, but since 1980 and operating 2 remote Ontario resorts I have never had a motor damaged or freeze up over winter storage. I cannot speak for other lubricants, I am no authority, but I know what works for me. I have several Outboards run at this ratio with over 3500 hours on them. Sorry for insulting everyone's experience. But when you "tell the truth, you don't have to remember what you said".

Add note: 100 to 1 is not acceptable on any oil unless it has been proven for many years. OMC did screw up with that. How about the self mixing gas cans? Give me a break, only in a perfect world. Tolerances were no different from 1992 to 1993 designs. The same materials were used in bearings, sleeves, pistons. If 100 to 1 Amsoil works on 92's, it will work on 93's. The only difference is that OMC realized they were stretching the ratios, nobody is perfect. Just like they scrapped the self mix cans and early VRO systems.

The key to long engine/motor life is high quality lubrication at lean ratios to minimize carbon buildup. Check out this 40 to 1 6hp, 1966 Johnson…

“I will post photos that will provide strategic evidence to suggest that I am correct shortly”
 
This post is about oil in the test tank anyway, not about our beliefs on oil ratios, really I guess I woke sleeping dogs. Sorry folks, but 100 to 1 with Amsoil pre mix has not failed me in operation, or storage in 38 years. Give me needle or ball bearings in my outboard and I will be proved correct at 100 to 1 with this product. Now lets talk about something more relevant, like ethanol. Lets start burning up Outboards.
 
Here are the photos of a 15 Johnson with 3000 hours on Amsoil™ at 100:1, and a 1966 Johnson 6 with only 1000 hours that ran (petro base) two-stroke oils at 40:1. My shop is full of examples, but rarely do I have to dismantle an Amsoil motor. You be the judge. A picture is worth a thousand words.
