Author Topic:   Source for Propeller Shaft Seals for 2003 Johnson

ronniet posted 06-07-2009 09:04 PM ET (US)
Once again the never ending problem that is my 2003 Johnson 175 requires my attention. I've got myself some kind new problem! I was cleaning the Johnson on the ears after having the engine in the trim-up travel position for one day after use, when I noticed that upon trimming down green gear oil began to flow out of the propeller exhaust hub. Closer examination revealed that seal seemed to be the source of the gear oil, or at least there was gear oil evident around the shaft seal.
My Seloc manual says that there may be an underlying problem possibly bearing wear or other damage causing my seals to fail; this could be the case.There were no incidents prior to the leak nor was there fishing line or debris around the propeller shaft causing failure. I'm also sure that it happened on or as a result of my last outing.
I want to replace the seals and gear oil and see if that solves the problem before I overhaul the lower end.
Where to find the parts or kit I will require? Feedback on possible causes would also be of value to me as well.
Thanks. Ron.

Thanks Jim
I ordered new prop shaft bearings too I hope this is the problem,still some feed back would be great!
Thanks Ron

I just recently resealed the lower unit on my 1983 Evinrude 75. On my gear housing on the propeller side of things there are 3 areas of possible leakage. The prop shaft. oil has to go past a double seal there. Mine wasn't leaking there and showed no sign of leakage. The next area was the o-ring seal around the whole bearing housing where it slides in the case. After disassembly my seal was very flat from age but didn't seem to be the problem. The next area was the bolts that hold this bearing housing in the case. Those bolts down in the prop housing are small bolts with large heads and integral o-rings under the heads. One of my bolts had a cracked head allowing the o-ring to deform and was where my probable leak came from. I would suggest that you take a look at these bolts if you have them. They are not installed very tight and if loose or damaged will leak oil. In my manual they suggest using thread locker and sealer in addition to the o-rings on those bolts. My problem stemmed from a drive shaft seal failure allowing water in the gear case and over pressuring the seals and resulting in leakage in the weakest seal. I was lucky as this gear case was 26 years old.
I can only tell you of my experience as I know nothing about your gear case and how its assembled. This was the first time I dealt with a gear case and I was successful in resealing my unit. I bought my parts from Marineengine.com
and they did right by me. Not having done this repair before I had to buy parts several times because allot of seals are not readily apparent in the old manuals. I kept finding things I didn't order.

Thanks Steve,
I just received my parts-bought them from the link Jimh posted.
I just finished removing the bearing housing in my 03 Johnson 175.nothing really seemed a miss,but just in case I'm going to replace all seals,o-rings and bearings. the original leak was very apparent,the tell tale sign was the milky green oil around the front bearing seal.this may solve the problem it may not.Something made it leak suddenly,and I'm not sure what.You mentioned that the pressure inside the gear case could have forced out the gear lube,but why did it take sea water in?
Another question is raised about the bearings now!Will new bearings be compatible with the old race on the prop shaft?
I respect and consider all suggestions from every reply but seahorses input would be word!
once again thanks Steve

The water came in under the seal under the water pump. Enough pressure from the pump to force water past the seal. Temperature changes expanded the fluid and leaked out the weakest seal.
