Can't locate part for S150TXRV

I can't seem to find a part in the online store here. I have a 1997 Saltwater II 150 serial S150TXRV.

I am trying to replace the roller cam that attaches to the carb linkage for the throttle. It has a flat spot. I found the accelerator cam under "control" in the online scematic, but I cannot find the roller cam. Any help with this?

Thanks in advance.
