2012 Yamaha SX210
First thing I will say is the Ridesteady works great, what a difference it made for me to be able to wakeboard at a constant 19mph behind my own boat. Generally I never got to ride due to other drivers not being able to control the speed well.
Installation was very easy, I took my time spending about 5hrs for the complete install, but took care to route the wires nicely. I did have to correct one mistake I made early on, I was facing the back of the boat and mounted the port control on my left side, oops, but easily corrected.
As shown in my pictures, I did not need to remove the dash, as I was able to access the back from behind the bow seating. There was a nice piece of plywood fiberglassed in to hold the stereo support with made a great mounting place for the control electronics. The GPS receiver was mounted in front of the windshield, under the fiberglass, so far it works well there.
