Both the ThunderJet Alexis Outboard - 20 ft. 2008 and the ThunderJet Rio Classic 2013 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 Rio Classic 2013 tops out at 320 hp. Engine specs for the ThunderJet Alexis Outboard - 20 ft. 2008 aren't listed - confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the ThunderJet Rio Classic 2013 carries 80 gallons versus 50 gallons in the ThunderJet Alexis Outboard - 20 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.
