Are there any cast iron manifolds with a dry-joint that can be used to replace the ones on an rtp-1?

Did master craft ever fix the problem with the ETX manifolds where they corrode at the welds?

I use my boat in salt water and am in need of new manifolds so I'm trying to get the longest lasting thing I can get under 1k.

If your running an open cooling system, in the long run...Stainless is the only to go. You don't want to run the ETX. They are high maintenance, even in fresh water.
