Here we have a brand new Antenna and cable/thread which will be able to fit all Waverunner boats however, please note, that if you have the older version of boats on 40mhz (remote has telescopic aerial) then you will require a slightly larger hole to be drilled in place 

of your old aerial thread on your boat (now discontinued) and also note as you will see from the pictures, you will need to join the cable to the cable coming from your receiver box in side your boat (solder is best)

The last picture shows what it will look like once fitted
