Bushwacker,
you're right, wood does rot faster in fresh water,than it does in saltwater.
I had meant to say that the brass tubes would be more likely to corrode quicker in salt water than fresh.

As for changing them,I figure at my age,they should last me plenty long enough,and if not,I'll have someone else do the work.
After that,it's the kids problem.
