410 or 190 and for what? to bring it in?

oil are you sure?

you usually get fuel spills through the intake and combsution chamber depending on what stroke it is...

can you take out the plug? do so..is it full of oil? .drain fuel if any from carb and report back

if the cylinder is full of oil then I would first dump what oil it still has, take plug out...drain upside down...

then you can if carefully pour some gas in there and "wash" out the oil...then let evaporate again...cycle through a couple more times to expell as much residue as possible

the same applies to the carb...iuf unfamiliar with carbs then it might be a bit more of a challenge for you but its not rocket science basically a good clean and wash of the jets and floats and all and your good to go

get some good new gas in her and try to fire it up...with a new plug or plugs

good luck

oh forgot your intake is probably soaked...if it has an element takle it out...rinse in your favourite solvent or air cleaner spray...air dry

then do the same to the intake clean off all residue...dry as much as possible

the try spraying some wd40 or carb cleaner in intake while cranking over(wuthout plug)

what you are trying to do is eliminate all traces of oil and sludge from both the intale and combustion chamber as well as the piston top, rings etc...

you dont want to start the engine with a lot of oil inside as its possible to do damage this way and if it starts and runs you will smoke badly and soot up and carbon up your piston leading to sever pinging...which is bad.

after it starts and runs fine...you can mist the intake a bit or better yet run some strong mix of seafoam in your first tank of new gas

this will clean up crap from the valves, piston, and combbustion chamber without having to tear it down

peace

oil can definetly come out guys...usually through the "vents"

motorcycles suffer from this if spilled for a lomg time same thing with the fuel it will spill into the intake and flood the engine

easy enough to pull the plug and see if there is oil...same for the carb

good luck

btw if its real thick oil from lower unit thats not possible unless you have a bad filler or lose plug at the bottom it would be easy to see if its that as it would be visible no?

cheers

couple links to help you out with similar if not the same issues

http://www.boatdesign.net/forums/outboards/new-mercury-6hp-leaking-oil-36285.html

4 Stroke Outboard Oil Pressure Problem in Outboard Motors Forum

in this link they are talking about what Im talking abot and basically on how 4 strokes benefit from storing certain ways...one being on the compression stroke so oil doesnt leak don the valves into the cylinder

the other on how oil will pull in the valvetrain and trickle down...

the other on how 4 strokes will have vents you need to find where those are...they cant work unless the pressure inside the "crankcase" is ot released some way

on motorcylces I benefitted from always leaving the kicker at btdc...valves closed so no oil would pool down

you would sometimes get no compression cause the valves would stick open too cause of rust forming on the seats...a whole nother issue btw...but applicable

anyways check the prop EXHAUST PORT that maybe the source of your oil leak

cheers

ok bud so I see 2 issues

like the links I posted you have oil coming out the exhaust through the prop from sitting in this position for a while

2. the intake looked like it had oil in the black part...tube

when you can stand the engine upright...

check oil level after standing ipright a while the go ahead and take he plug out...

clean it up or get a new one...flush out if needed...

yup, some engines have foam filer elements...usually o outboards there is just the intale tract...

its pretty simple to take off the carb...some use clamps, or screws or whatever...

draining the bowl is easy to...this will make starting easier and if you can a quick check of the jets and such wont hurt....

ps. youd be surprised how much a little drops of oil spreads especially on cardboard and even a drip a day will expand like crazy...

did the oil filler cap look wet? was it really well sealed

youll be fine...

changing lower unit oil is a walk in the park...since you did have oil come out the exhasut check those seals if you can...
