Shifter switch repair 2003 Sea Ray Sundancer 380

[bcoolman]

My shifters stopped going into reverse. I can reverse connections at the transmission and it goes into reverse. Once side was fixed by messing with corroded shifter switch control made by Zippy. Where can I find a replacement part or identify the part number for certain. Thank you. I think this is a photo of the part that needs to be replaced but that may be neutral safety switch and I think my issue logically must be the electric shifter switch(s). 2003 380 Sundancer part #1413863
