Noticed a strange rust mark on the side of one of my mercruiser inboard manifolds near the cast lettering near the middle. It's not wet but suspect it's a crack starting to show. As far as I know they are original to the boat from 2003. What is the best case repair for this? Just the manifold or should I replace the risers as well? I'll try to post a picture soon. TF
