Do I need to replace my exhaust elbow/manifold?

[MikeDobbs]

Hey everyone-

Working on a mercruiser 3.0lx and just took the exhaust apart to inspect the exhaust shutter and found a good deal of corrosion on the elbow and possibly manifold. I am really hoping not to have to replace these items this year (in particular the manifold), but I don't want to push it if they are already beyond their useful service life.

If you can please take a look at these pics and let me know if you think I need to replace these, or if I can just clean out and possibly plan on replacing at the end of the season?

Thanks!

Ayuh,..... She looks tired, but ya gotta clean it up, before you can evaluate it,....

Take a flat file, 'n clean the gasket surface, so you can measure the remainin' iron,...

Ya need 1/4", I believe, 'tween the exhaust, 'n water passages,...
