Where ar all the Trolling Valves ?

[Paul Burgoyne]

I just purchased a 30" Rum Runner and would like to do some salmon fishing from time to time but I can't find a trolling valve for the ZF 63A transmission. It seems that no one stocks it and the manufacturer is back-ordered. I would love to find a new or used one if anyone knows of any in North America. The part number is ZF#3312001018

Any tips would be helpful.
