TMRC FLAT TRANSOM OUTBOARD BRACKET ADAPTER

Run the newer TMRC outboard system on flat-transom hulls — no custom drilling.

This adapter mounts TMRC outboard brackets to flat-transom RC boats, letting older hulls and legacy builds run the newer outboard system using the existing bracket mounting pattern.

No guesswork. The part bolts up clean using the bracket's four factory mounting holes.
