Howdy all, Well after my lower unit issue and prop issue, I finally have the "old Mac Attack" up and fishing well, My question is I tried changing the oil in my ad41 and it is equiped with a seperate tube for sucking th oil out, I was only able to get 6 quarts out before it started sucking air, any recommendation is this normal, ????? It would seem that the tube should go all the way to the bottom of the pan, do these tube have issue or break? thanks. Erik
