Only time outside is when they were in use. Polished and waxed twice a year.
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 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
