Both the ThunderJet Alexis 2009 and the ThunderJet Maxim Classic 2010 are modified-V designs, both built in aluminium, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
The ThunderJet Alexis 2009 carries a rated maximum of 325 hp. Engine data for the ThunderJet Maxim Classic 2010 wasn't available in our records - check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the ThunderJet Maxim Classic 2010 carries 80 gallons versus 50 gallons in the ThunderJet Alexis 2009.
