steel or aluminum and what type of water do you boat in? use a magnet it wont stick to the aluminum exhaust manifolds. if its in salt water i would go ahead and replace. if its in fresh your honestly probably still good with either manifold.

Flush after every use. I dont think the 496's have as big of a problem. I've been boating in FL for 10 years now and the only time I have issues is when I dont flush.
