Is there no balsa core where the head's seacock is? I'm going to replace a transducer that is in that area and want to know what I'm getting into. It seem that there is a square area where the inner skin dips down, my guess is there is no balsa core in this square?
If anyone has any tips on replacing the existing transducer that would be helpful. The new one will be the exact same diameter. It seems the biggest challenge is getting the old one out. I would like to avoid hammering it out, so I was thinking of cutting it up with a rotary tool.
