I've had 9 of the 300XS motors so far. They run 104-105 on the 21 Liberator cats. That's the same speed as the 300x ran. We ran 84 miles, 60 of them were over 90 mph, and used 19 gallons. A customer ran 40-50 mph with his family one day and ran 198 miles using 32.5 gallons. That's over 6mpg.
Does anyone have any pics of the new 350?
