ThunderJet Alexis OB OS 2011 vs ThunderJet Alexis Outboard - 21 ft. 2008 — Same Brand, Different Boat
Matching a deep vee ThunderJet Alexis OB OS 2011 against a modified vee ThunderJet Alexis Outboard - 21 ft. 2008 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
The ThunderJet Alexis OB OS 2011 carries a rated maximum of 300 hp. Engine data for the ThunderJet Alexis Outboard - 21 ft. 2008 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the ThunderJet Alexis OB OS 2011 carries 48 gallons versus 5 gallons in the ThunderJet Alexis Outboard - 21 ft. 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 6 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The ThunderJet Alexis OB OS 2011 and ThunderJet Alexis Outboard - 21 ft. 2008 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
