1975 Johnson 6HP Water In Lower Unit

[gnarbrah]

Hello all - now that I think my little 6HP will be back in running shape soon I figured I'd check the lower unit oil. I had noticed a drop or two under the motor (stored upright) coming from the back of the prop. I pulled the drain screws and a solid cup of water came out before the black sludge. I went ahead and pumped it full of fresh gear lube and sure enough it's dripping from the prop shaft seal again without even running the motor. I've contemplated rigging up a pressure tester but I'm fairly certain of what I'll learn. That being the case I'm going to give a go at replacing the seals (might as well do the impeller while I'm in there). Question - Is it a tough job? I'm planning on just replacing part numbers 314167, 313282 and both drain plug washers. Sound right or should I do some other stuff while I'm there?

Thanks!

oops - forgot I posted about this a week ago - sorry! I got one reply and it was mentioned it might be the shift rod o-ring as well? Any idea what part number that is and what that's like to get to?

Pressure test it so you know where all the leaks are.

No Title

So I found a few minutes today and pilled the lower unit off. A few items:

It still has the original metal impeller housing - should I get a new plastic one? It has a little bit of wear marking from the spinning impeller but overall looks pretty good.

There appears to be a lot of water in the area (see pictures) and under the impeller plate it looks like gear lube has found its way up.

Next step is to build a pressure tester and see what I can find out.
