Title: Exhaust Manifold replacement intervals on I/Os?

How often do you guys replace your exhaust manifolds/risers on I/O motors when used in freshwater exclusively?

Never.  But...my boats are winterized every year with antifreeze sitting in them helping stop any corrosion.

I replaced mine after 35 years. Now they are stainless... So probably another 50 to go.
