I need conformation before I put this behind me!!

[fishnhunt]

Well today I went and checked the cup I have been letting my L/U oil sit in for about 2weeks. I had mentioned in an earlier post that I thought I had a significant amount of water in my lower unit, due to the oil looking milky (walmart marine oil is what i use). Well i examined the cup today and the oil looks fine now. It appears to be a normal brown color instead of that gold milky color i noticed 2weeks ago.So i am guessing that my water intrusion in my L/U isnt really anything I need to worry about due to not having and inch or so of water settling at the bottom of the cup? Can somebody please confirm to make me feel better about my decision?

replace the seals on the drain and vent screws, # 1 place to leak. buy several seals, and keep watching for water. chocolate milk shake is not good.

I think a better way to check is to fill it put fresh drain and fill washers and run it a few trips and check the oil again.If its milky like coffee with cream you have water intrusion.Its possible if you let it rest awhile before you drain you may get whatever water allready seperated.If it doesan't seperate then
it would seem its a low amount.I know some of the old timers with leaky E/J gearcases just change their oil more often.Synthetic is said to be biodegradeable.And I supose a guy could let it settle out a reuse oil that is relatively fresh.

You definitely have a small amount of water intrusion. You can just change the oil a lot. But its probably the driveshaft seals which arent that hard to replace. The driveshaft turns twice as much as the prop shaft so it wears faster. I had the same problem.

If there was no water settled out of the oil, then there is no need to replace the seals. The "milky" color you noticed upon draining may have been aeration of the oil (lots of tiny air bubbles in suspension) , rather than water, particularly if you drained immediately after use.

I recently bought a used boat/motor and was going to use the Walmart L/U oil kit to replace the oil on my E115TLCR D
Anyone recommend against that kit? Like the fact it came with the little pump tool and everything to make it easier.

While I had the screws out, I was going to replace the screws and the seals (Drain/Fill and Vent Screws)
Anyone know where I can find this part? Are they all the same or do they change with different years/models?
Thanks for the help!

And can someone go into the process of replacing the driveshaft seals?
Like process and where to find the seals, etc?

the walmart super tech oil is fine. it is rude to hijack another persons thread. you should have started your own.

"...isnt really anything I need to worry about due to not having and inch or so of water settling at the bottom of the cup?"

Don't let me get too picky with ya, but...if you had a half inch, or a quarter inch, or 5 drops of water in there, you might not need to worry about impending doom exactly, but you would want to take some action. If that makes sense?

Most common source of leaks: shift shaft o-ring. Easier change even than driveshaft seal. To detect and pinpoint the source of a leak, pump 12 PSI or so of air into the gearcase and wait. If pressure leaks down, submerge it and look for bubbles. Or splash some dish soap around the seals. Your L/U gear oil change pump hose and fitting is perfect for the purpose.
