Blue smoke on start.

danno1 · Oct 15, 2006

Hi everyone. My 88 200 evinrude always smokes blue after start up. When running it seems fine. I`ll shut it down ,and after running, it stills smokes when started. Could this be the VRO ? If not, what would cause it just on start up ?
Thanks

Recirculation check valves could be blocked or allowing flow in both directions. Also you could be running cold.

I'm not sure you have an issue. Just residual unburned fuel in the cylinders and block.

Water shows up as white smoke.

2 strokes with carbs smoke at start up.
i have not seen any that didn't.
After running a bit it will diminish but still smoke.
If you look like you are fogging for mosquitos there may be an issue but signifigant smoke on a cold startup is pretty much normal.

I think you are a candidate for a decarb my man....

Decarb can and will eliminate that smoke you are talking about. It also has done it on my 50 year old diesel farm tractors. Believe an original nonbeliever......it works. d

I am assuming you are using TWC3 rated outboard 2 stroke oil and not anything else?
anything else would most defineately smoke alot and will not work properly.

Not sure I share your enthusiasm Kevin.

Blue smoke on start.

Sounds like a little more oil flowing than needed. Also you may be running engine without letting it fully warm up? Doesnt sound like any thing major going on. Decarb is a great idea also. Good Luck!

Actually, it does it starting cold AND hot. I tried switching over to Pensoil full syn. with negative results. I haven`t tried the Seafoam treatment yet.
Its always at startup, even after running 20 minutes. Shut it down, then re-start. It does the same thing.

Re: Blue smoke on start.

Well do the seafoam then go back to your pennzoil syn. I did it to mine and the only way I know it's using oil is by seeing it disappear from the tank.

Sounds like you are really crudded up so you may want to do the decarb thing twice......then keep it in the tank per can's instructions.

Re: Blue smoke on start.

Will do. Thanks Mark. I know its using oil, because I have filled the oil tank 3 times, this summer with synthetic.Does it matter if I wait till spring, or do it when I winterize it with the carb treatment ?

Re: Blue smoke on start.

I know for a fact BTDT that syn burns cleaner than pet oil. Knowing that, if I got her all cleaned up with the decarb thing, I'd surely want to keep it clean.

But it probably won't make any difference if you are just going to run it a few times on pet oil.
