My Boat is a 07 Malibu Wakesetter VTX
I was able to purchase a couple of actual surf gates from my Malibu dealer that were used. I purchased the Lenco Fast Actuators: 102F Fast Movement Actuator -12 Volt | Lenco Marine SKU:15129-001, as well as the Wakelogic automatic GPS controller. Please watch my YouTube video attached for the step-by-step detailed instructions.
