What the ...?
 

I just bought a 23' with 2-175 hp Johnsons. The engines are 1996. I ran them in the driveway yesterday. Today there is an 6" oil stain under one of the motors. The oil seems to be coming out of the prop. Any ideas what this may be? Just found it and have not fully investigated the problem.

Thanks in advance

I'm not an outboard mechanic but I would look under the cowling to be sure the engine oil resivoir is not leaking,if not then I would think the lower unit seals would be the next obvious culprit. The mechanic I use allways checks for fishing line behind the prop when doing a motor service,apparently it can eat up the prop shaft seal.

That sounds like the bearings in the lower unit are shot or maybe the whole lower unit is shot. You will need to have the lower units rebuilt if that is the problem. After about 10 years most lower units will have problems depending on the amount of hrs. are on the motor. Sometimes, “if you are lucy” it could be just 2 cycle oil running down the motor and onto the pavement. First thing to do is determine what type of oil is it.

Good advise above!

Next I would drain the lower unit fluid and make sure the fluid is not a "milky" color. That is a sign of water intrusion. Also look at the tip of the lower unit drain screws when you pull them out. They are magnatized. Excessive metal filings attached is a good sign of internal trouble [img]/images/graemlins/wink.gif[/img]

Re: What the ...?
 

All great points above.

Hopefully it is the following

It might just be the engines ad fellowship metioned...let me explain

I too have 1996 v6 Evinrudes, mine are 225's.

They have to be the most reliable engines but they leak so much "blow by" out the exaust hub it is troubling.

I have had this "issue" checked by my mechanic and he assures me not to worry.

There are a few differnces between your issue and what I am discussing.

1-I have never measured exactly how much oil is spewed out after running them but it is noticible enough to cause me to adress the situation.

2- both my motors do it

Also a little trick (unrelated to your issue but useful) I learned, and you may already know, is the 1996 Evinrudes have an advanced start feature.

when cold starting the engine, (first time)

Hold the key in the choke position for about 8-10 seconds. You will hear a click

after this click start the engine.

it should fire right up.

I was amazed how well it works.

Re: What the ...?
 

Thanks guys. I will let you know what the result is.

Thats what my neighbors said every Sunday morning.....http://www.clicksmilies.com/s0105/wu...smiley-001.gif

Re: What the ...?
 

Thats interesting Trayder. I wonder if my 1999 175 carb. has that feature. My outboard mechanis says thats how you should start most cars as well. Vezo.

Mike

My '99 250hp carbed doesn't but I go thru the motions anyway trying to stop the sneezing [img]/images/graemlins/tongue.gif[/img]

Brian

Did you discover the problem if any [img]/images/graemlins/confused.gif[/img]

Re: What the ...?
 

If Chuck's 1999 does not have the feature than I would doubt it.

I do not know the years that had the advance start feature (if in fact that is even what it is called) but will do some research and find out

Re: What the ...?
 

Answers on the starting questions:

1: It is called "quickstart"

Every time you start the engine, QuickStart electronically advances ignition timing 10 degrees until the engine warms up. If the engine is already warm, it de-activates after about 5 to 7 seconds. ( I got this info from "jegervais" at Iboats.com)


2: Quickstart is on OMC engines from 1989 and up.....
So according to my local OMC dealer (Don's Marine) both you and Chuck have this feature.

Re: What the ...?
 

Hmmm, that's interesting. I never knew my '89 Johnson 225 had that feature. I always thought my engine's starting problem was due to age. Now I know what to do this season. [img]/images/graemlins/cool.gif[/img]

Re: What the ...?
 

Trayder is right, those engines jump to life when you do that. They just would turn over until I tried it and they fired right up.

Chuck,
The early diagnosis is blow by through the hub exhaust. Just seems like a lot of blow by. I will let you know if I learn any more.

The weather here has been cold with rain every other day. Just can't seem to get a full day to work on the boat.

Re: What the ...?
 

I had a '92 25 Rude that would do the little oil puddle under the prop. It was oil residue from exhaust.

It bugged the hell out of me, as it just left a mess all the time.

Re: What the ...?
 

Jason, very cool verification. Thank you. Did not know that. Mike.

Re: What the ...?
 

My old mercury is an oil dripper ... through the prop ...

Seem to recall a members 300 hp Black Max blowin all sorts of nasty out the prop when we fired her up a last year [img]/images/graemlins/shocked.gif[/img] [img]/images/graemlins/grin.gif[/img]

Re: What the ...?
 

It's all good yo. [img]/images/graemlins/grin.gif[/img]

Re: What the ...?
 

Jason, I don't hear that "Clicking" sound like your motors when I try it. I don't know how to tell if the timing is being advanced [img]/images/graemlins/confused.gif[/img]

Re: What the ...?
 

My old flats boat with a 70 Johnson did the same thing.
It came down to the oil. TCW3 is todays standard.
A friend (I know that is hard to believe that I have one)
did an oil test with all the major brands. Mercury TCW3
was the best, it had more of the crucial properties than
any of the others. When I changed brands the problem went away. I use Mercury oil in my Johnson, Mercury, weed wacker and blower. I will scan the results and post them for all of the oils that he did.
See ya, Ken

Ken

I burned up my weed whacker using TCW3 in it [img]/images/graemlins/frown.gif[/img] There is a difference between air and water cooled 2 strokes [img]/images/graemlins/blush.gif[/img]

Re: What the ...?
 

Maybe my motors are "special" your neighbors sure seem to think so!!!

Re: What the ...?
 

Capt. Chuck,

I don't hear a clicking sound either, I have a series of lights on my gauges after all of the lights are lit, it fires right up.

Bones,

Is that the quicksilver?

Re: What the ...?
 

Chuck, I spoke to my source who did the attached tests on the oils, There is no difference in water cooled and air cooled oils. His words were 2 cycle is 2 cycle only the manufacturers. Mercury has the most Molybdenum, which lubricates and bonds to the metal. Mercury has the highest content of any of the ones tested.

Thanks Ken, I stand corrected. I quess the lawn mower repair shop was trying to get me to buy a new one [img]/forum/images/graemlins/tongue.gif[/img]
