Replace corroded, broken pin of Raymarine sonar gps

A pin corroded and broke from the transducer/power connection on a Raymarine Dragonfly sonar/gps display. The pin that broke is the bottom right pin, which brings power to the unit.

Wondering if possible to replace a pin? Alternatively, I do have a different Raymarine unit (non-functioning due to corrosion in micro SDHC card socket) with all connecting pins — perhaps possible to remove the good pin socket and use it to replace the broken socket?

I have contacted Raymarine several times. Raymarine replies that the unit is no longer manufactured, and they no longer service these units.
