On my Merc 500 (circa '76) the timing pointer is broken off. I don't know if I did this or my brother before i got it, but I can't find it on any parts website and there's no scrap yards for boat motors in about 100 miles...Does anyone have a picture of it they could link so I can compare and maybe make a custom one to fit? It's the black plastic pointer on top for the timing marks on flywheel. Any help is always appreciated!
