I torn down my 1989 Johnson 140 HP outboard before Christmas to rebuild water pump. Put it back together today and may have switched o-rings. Where does the fattest O-ring go in the water pump? I put a narrower one under the impeller on top of the flat plate and am now thinking that is where the fattest o-ring was supposed to go. Anyone sure? Maybe the fat one goes on top of impeller housing?
