Re: Water in Oil 1957 Johnson AD-11 7.5HP

First thing……Don’t take the lower unit apart without photographing every thing as you go. The first time I rebuilt one with new seals, etc., I laid everything out exactly like the parts were together in order, and I took photos so if I had problems I could see the order they went back together and which direction they faced. It saved me from screwing up and it worked perfect when I re-assembled it. The string seal (spaghetti seal) between the clamshell halves is a bit tricky, and if you search around you can find info that will help you. You will need the proper sealant for this part also. There are different ways to replace the shaft seal, but a dedicated tool seems to work best for most folks. I have read about making a tool on here someplace, but I can’t remember where.
