1980 Johnson 60, milkshake from weephole

[cedar999]

Hi folks, great forum!<br /><br />I have a 1980 Johnson 60hp 2cyl. I drained the lower end as part of pre-season maintenance this weekend and got the dreaded milkshake, a real creamy one. I replaced the oil because I wanted to test the powerhead, and when I filled it I started getting some weepage out of the little weep hole just below the water intake. I've read here that the weephole is there to vent unburned fuel and oil.<br /><br />I went to pick up a water pump and a set of seals yesterday, and the fellow at the counter suggested I might have a bigger problem - corrosion inside the lower unit.<br /><br />Is this common? If that's the case would my best manoeuvre be to toss that lower unit on the trash heap?<br /><br />Any help appreciated.<br /><br />Paul

Well, I just pressure tested the l/u and the driveshaft seals are obviously at least one problem. And they are so bad I can't tell if there is another problem.<br /><br />I had a frozen impeller and may have destroyed those seals while trying to remove it (pliers, penetrating oil,heat, hammer, chisel, cursing, swearing, etc...) so I may still have another problem, but...<br /><br />Since I have to replace those seals anyway to test further I looked at my OEM manual. Do I understand correctly that I have to remove the prop bearing carrier, etc, then remove the driveshaft to change those seals?<br /><br />Any help appreciated.<br /><br />Thanks,<br />Paul
