Water in gear case

[SweeperForce]

Hello,
How common is it to have water in the gear case? I changed it this weekend after only 5 hours of run time and it was milky again. How difficult are the seals/gaskets to change to prevent water from entering the gear case.

I have a 1988 125HP and it was pretty straight forward. Hardest part was pulling the spool assy. out. Mine came out relatively easy, however, if you have corrosion, it may be more difficult. Next hardest part was getting the shift linkage put together correctly. The manuals are not real clear, but after a little trial and error, I finally figured it out. If you have a manual and basic mechanical skills, you should be able to do it. I was actually surprised at how easy it was.

Before you go tearing the lower end apart, double check the gaskets on your "Fill" and "Vent" plugs. If they're bad, they will allow water into the lower end. Much easier and cheaper than lower unit seals.

Not hard.Just make sure you pressure test it. That way you know for sure where it's leaking.J

Are any special tools required?

Should the case be full of lube when you do the pressure check?

There is a special puller for the spool, and several other special tools, but they are generally no longer available. If your motor has been used in fresh water, you shouldn't have too much trouble getting the spool assy. out.

Not sure if it needs to be full of lube or not. I've done it several ways, empty and full/half full. What is most important is that it should hold a constant pressure and not drop down as it sits.

Empty.If it has oil in it,under pressure it can make the seal swell and not leak.J

Its pretty easy to do, I changed mine a couple seasons ago.

I made my own spool puller, just got a piece of 1/2 thick steel and drilled 3 holes in it. One in the center for the prop shaft, and the other I ran some all thread through and threaded into the two holes on the spool. Just put some nuts on the all thread and crank it down till the spool pops free.
