The gold one is a 2010 FX Cruiser HO with the excellent 1.8 liter Yamaha marine motor used in all their modern Waverunners and boats. The red one is a 2008 FX Cruiser SHO with the 1.8 liter supercharged motor. The current hour meter for each is approximately 135 hours. The red one has a little more get up and go, but both top out within a few miles per hour of each other. For more detail text me here 56
