On my 68 120 mercruiser, the manifold block off plate rusted through and leaks..I did find a replacement..But am thinking I am putting my motor at risk by not getting a new (or dang near new but used) exhaust mani..
There is a lot of rust in the 42 year old mani..is there any set thickness like rotors, at XXXXX mm's they are shot?
Is there any rustproofing/coating/miracle in a can cure for the red cancer inside the manifold?
