Under dash Backing Ring for 2018-12 Yamaha FX Waverunner Cup Holder Mount

This is a custom machined under dash backing ring for the FX Waverunner cup holder mounts. It is made out of 1/4″ thick black marine grade U.V. stabilized plastic and has a black matte textured finish. It is used in combination with my custom machined cup holder mount for the 2018-2012 Yamaha FX Waverunners and is recommended when mounting 7-9” chartplotters.

Please Note: This item only ships with the purchase of a matching 2018-12 FX cup holder mount. Existing customers may contact me via email for a price and shipping information.

Six equally spaced 1/4″ screw holes have been provided through the face of the ring for fastening to the dash. Installation requires removal of the right sided Waverunner panel and then using the six existing holes through the dash around the cup holder.  Removing the side panel is very easy. It only takes a few minutes to take it off and a few more minutes to put it back on. Removing the side panel will make easy work of tightening the fasteners and routing your sonar cables. The ring may be retrofitted to an existing cup holder mount simply by making a single saw cut to one side of the ring between two fastener holes.
