hello. i have recently purchased a new timing cover for my 3.0 4cyl, mercruiser. the new cover has no timing tab with marks to time engine.as the old one did. and there is 2 threaded holes missing (on new cover) that the front of oil pan bolts to bottom of timing cover. i can probably drill holes and put nuts in. i just wanted to ask if anyone else ever had too deal with this. thanks
