This is a custom machined Yamaha FX Waverunner multi-mount plate and double RAM ball arm adapter kit for the 2019+ FX models.
The kit includes all needed pieces for one assembly.
Accessories offered by Yamaha typically use a 1” mounting ball. This kit provides two 1-1/2” balls (also known as a RAM size “C”) spaced six inches on center.
It provides a strong one-sided double RAM ball mounting solution using the existing Yamaha dash holes and is well suited for holding a GoPro, speaker, cell phone, GPS/sonar fish finders, or any other devices having two 1-1/2″ RAM balls.
