Hi, I own an '86 Bayliner with a AQ131A 4 Cyl. Volvo Penta motor. We changed the timing belt and the notch on the cam pulley seems to be off about 3/16" from the mark on the valve cover which is almost a tooth. Also the mark on the cover is just a sticker which makes me wonder how accurate it is. The other two pulleys seem to be lined up good. Does this sound like a problem?
