I was working to replacing the zinc for our condensing tower on our Sea Frost engine
drive system. We've had the boat a little over a year and this is our first time to replace it.
To make a long story short I removed the brass plug
and can see that the finger zinc broke off inside the column. We've been able to see/feel the piece of zinc in there a few times while trying to get it our but not had any luck with removing it. We've tried using water
pressure to push it out by opening the seacock, but no luck. It appears there is a lip just inside the hole where the zinc threads in place that is preventing it.
Anyone have any magic suggestions for how to get a piece of zinc out of a small hole in a plastic tube? We're currently working with a piece of coat hanger, trying to carefully work it out but not making much progress.
I must say this seems like a horrible design, but we're stuck with it. The good is that water
enters the bottom of the column and exists the top, so I guess in theory it's possible the piece could stay at the bottom in there and not cause major problems. That being said, for obvious reasons, we want it out.
