3000 sleds got the same 700 twin 4 stroke as the wildcat trail/sport machines.
They received the 3000 moniker because it makes more hp than the 570 fan in the 2000 series, and less than the 500 twin in the 4000 series. (also 2 strokes used even numbers 2000,4000,6000,8000 while the 4 strokes had odd numbers 3000, 5000, 7000, 9000)
