Oil Coming Out Prop !! W/Photo !! PLEASE HELP

[OneLuv1979]

OK i purchased this boat in this past spring ... The motor is a 2004 Johnson 115hp 2 Stroke !!!
After taking it out a few times i noticed that when i would run the boat in my driveway it would spew oil out the prop and onto the wall of my house !!!

I took it to my local dealer and he explained to me that it would be the Oil Injection , so he removed it , and my plan was to top off the tank and fill it with the proper amount of Oil 50-1 .... Well for some reason he decided to mix the oil himself till he got the mixture he thought was proper .. WTF ?

I then pumped the gas into a glass to look at it and it looked lean so i added extra oil , and now again im having this spewing problem and its getting pretty bad .... My father thinks its the lower unit but the lower unit was pressure tested when i bought the boat and the lower unit oil looks more grey the black ..... If i run the motor for 5 minutes at idle in my driveway this is what i end up with .....
( these pics are 2 days apart 5min of running at idle and after 30-1hour this is what i have )

I dont think the lower unit is leaking but this much oil going unburned ?
Is this possible ?

Love to hear some feedback from some of you guys who might have experience with something similar ... ANY HELP WOULD BE MUCH APPRECIATED !!!

DAY 1 , RAN MOTOR FOR 5 MIN AT IDLE IN DRIVEWAY ...
(this was 30min later , it got bigger after a few hours)

DAY 2 , RUN FOR 5 MIN AT IDEL ....SAME RESULT MAYBE A LIL WORSE !

So what you are saying is that you have no idea what your fuel/oil ratio is that is in the tank?
I would guess that if the engine smokes when running that you have enough oil in it.
It is not uncommon to see that type of leakage when running on muffs, you woun't see it when running the engine in the water.

I should probably also add that after the boat has ran and sits in the water for a few hours i have a hard time getting it to start ... My mechanic told me to fill it with non ethanol fuel and that should stop ..... I call B.S ...

Is it possible this has something to do with that ?
If the motor sits for 24 hours or so it starts right up fine ...
weird ...

Daviet correct i made sure that it was rich , but did not expect it to cause soemthing like this , is there a chance this is my problem ?
These pics show it after 30-40 min after i shut the motor down 3-4 hours later there is more oil then shown , alot is leaking ....

Really want to hear from someone who has seen or had something similar happen ...

Re: Oil Coming Out Prop !! W/Photo !! PLEASE HELP

What you are seeing is unburn't 2 cycle oil that has run down the exhaust housing and collected all the crap that's in there. It is normal to see something like this when running on the muffs, the engine does not get run at high RPM like it would on the water and the temp doesn't get as hot as it would when running on the water.
Either run it and burn up the fuel in the tank or get it out and use the proper ratio, even with the proper ratio you will see some of this when running on muffs.

Re: Oil Coming Out Prop !! W/Photo !! PLEASE HELP

I just dont understand how that much oil can go unburnt .....
I can not accept the fact that it will do this with the proper ratio ....
There has to be a better explanation how so much oil can get thru ....
This is extremley bad ...The photos do not show just how much came out after 3-4 hours ...
I know the oil is rich but dont understand how this much can get thru ...

How is not fouling out plugs ?

I am sure others will come along and offer more advice.

What's it smell like. Lower unit oil has a distinctive smell, just like what's in your car's differential.

Like everyone else has said it's probably just unburned oil that worked it's way through and collected near the prop, but there's a small chance it could be lower unit oil. Your nose should be able to tell you the difference.

I wouldn't EVER run an engine on fuel which I didn't know for sure had the right amount of oil in it. It's quite possible that you're running way too much oil through your engine.

thats deffinitly unburnt oil been there done that i would also check spark make sure all cylinders are firing with spark tester

"I can not accept the fact that it will do this with the proper ratio ...."
You are not running the correct ratio, you don't know what ratio you are running at this point.

Both of my 4.5 HP did the same thing. A good de-carb job can help alot.

Re: Oil Coming Out Prop !! W/Photo !! PLEASE HELP

OK if it is unburnt fuel what would you suggest i do to get it correct ?
My fuel gauge is not working , so i really dont know how much fuel is in there my guess is about 30gallons maybe less ...Its a 55gal tank ..
Not a easy task to burn that type of fuel with a 115hp and then i dont know when it will run out .. My mechanic is the one who mixxed the oil this way , and i added b/c i did not like the way the fuel looked ...Im sure its rich ...

I overoiled my Johnson 150 once(twice as much as needed) old age and CRS did that; anyway same picture as you have. Drain the tank; put it your lawnmower, car and anything else. Get fuel ratio correct and I think you will have solved your problem. Good luck.

Hmmmm interesting ... Now do you think this would explain it giving me a hard time starting after sitting for 2-4 hours ...BUT if it sits overnight it fires right up ...
Would love to kill both birds with one stone !!

If you still have questions, get a small 6 gallon remote tank, mix with the correct gas/oil mix, and do a test run. You may want to do a decarb to get rid of the unburned oil and carbon. I would rather have too much oil than not enough oil. Good luck.

Re: Oil Coming Out Prop !! W/Photo !! PLEASE HELP

Well, it will be a gradual solution to your dilema, but you could fill your tank the rest of the way with the correct mix and run it like that. It would still be rich on oil, but only about half as rich as it is now (and it's really not hurting anything to run it like that, except that your spark plugs will get fouled quicker than normal). Use fuel treatment/stabilizer and the fuel should be good for many months. Once that tank is nearly gone add however much gas you usually do that's properly mixed and you'll be back to normal.

I don't think you are going to correct both problems at the same time.
You know what is causing the oil leak problem, either drain the tank or run it out.
The hard start problem could be carb problem, needle and seat not shutting of the fuel when the engine is shut down. After it sits the fuel evporates and is not a problem. Do you know if or when the carbs were overhauled?
Hard start when hot can also be caused by an ign componet that gets overheated and when it cools off it will operate properly. You need to check the spark when it will not start, that will tell you if you have a fuel or ign problem.

Got ya ... If it runs for a while it will start back up fine , but if its sits for a few hours it wont ... So i would guess it would be somewhere in the carbs ..
Was hoping this run off has something to do with it ...

I will try and run it this weekend and burn some fuel ...
I do plan on topping it off with Non Ethanol Fuel before the winter ..
Im guessing it will take around 20 gallons or more , should i maybe mix 40-1 ?
OR i could buy some 5 gallon jugs and try and drain it the best i can if that would be the best way ....

Sort of lost but i do appreciate everyones comments ...

Re: Oil Coming Out Prop !! W/Photo !! PLEASE HELP

I don't think I would try and guess about the ratio. If you are going to add gas i would mix it to the proper ratio. The only thing that might cause a problem with a overly rich oil mixture is what you are seeing by running on the muffs and spark plug fouling. It will smoke a little more but that will stop when the proper ratio fuel works its way into the system. Remember to add something like sea foam to your gas for winter storage.

What's the temperature of this mtr when running. A cold running mtr can also cause this problem
