Yes the prop shaft seal needs to be replaced.Do this sooner than later as water will get into the lower g/box.Sometimes they wear out or fishing line is a bad culprit.Its not a big job but it really needs to be done.The oil will also need replacing.Hope this helps

Wait a minute It might just be exhaust residue see if water in gear case if it is real black it is probably exhaust soot from the motor

    I have the same problem and it is the exhaust soot. It never used to happen and now it seems to all the time. I do a lot of trolling and that adds to the exhaust residue.

There is a good detailed instruction on removing the propeller shaft seal and bearings in the SELOC manual. Worth the price. Tells you how to deal with the fact the bearing carrier won't budge. Worked for my 135 hp Johnson.

I believe you got fishing !one wrapped between prop and seal. Remove prop and inspect for line and leak around seal. If not, than the seal under water pump plate is leaking your gear oil.

After use I have oil coming out of the water inlet and the prop exhaust, could it be a gear box seal? it is an old johnson 9.9 about a mid seventy i think

It sounds like you need to change prop shaft seal. While at it check water pump impeller (in sure it is still playable). Also change seal under pump wear plate.

6hp Johnson outboard stalls & quits

go to an auto parts store and get a can of gasoline additive called seafoam. Read the label so you know how much to add to your 6 gallon tank. This stuff works wonders on outboard motors.

Gear Lube leaking from Prop

Keep an eye on it and put a bucket with paper inside under the motor. You want to know whether the oil is burnt oil from the exhaust or gear lube. You should be able to tell from the color of the oil. Its kind of like soot in a chimney, the exhaust goes through the prop with the oil you added to the gas.

Gear box oil leak

Here is a website where a manual for you outboard may be purchased.  Outboard Marine went out of buisness in 2000 and thus no parts of origial manufacture are support is available . Therir are secondary markets .    THe Lower case splits in half and their is a seal around the prop shiftm which is pressed in. The seal between the cases are cut o-rings which are placed and glued into place with gasket seal.
The water pump is located where the case splits a little bit higher. You must open the little port on the side and take out one of the screws to the connecting shift linkage to split the case. After splitting the case the drive shaft and water pickup tube(s) wil come out of the powwer head or the tubs may stick into the power head which is ok. Place the lower skag into a vice and remove the 4 or 5 screws to the water pump housing. Remove and replace impellor and impellor plate if available. If part(pieces) of the rubber impellor is missing flush out the tubes and the power head to remove them.   When reinstalling the lower unit use a flash light to make sure that the tubes return  to the proper place in the power head and the shift lever is resecured. If you need more assistance, just write back. I was an Outboard motor mechanic for five years about the time of your motor.
