Detailed Evaluation & Buyer Recommendation
ThunderJet Alexis Outboard - 21 ft. 2008 vs ThunderJet Bull Dog 20 ft. 2012 — Which Modified Vee Fits Your Needs?
When two boats share the same hull type — in this case both the ThunderJet Alexis Outboard - 21 ft. 2008 and the ThunderJet Bull Dog 20 ft. 2012 are modified vee designs with aluminum construction — 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 Bull Dog 20 ft. 2012 tops out at 320 hp. Engine specs for the ThunderJet Alexis Outboard - 21 ft. 2008 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the ThunderJet Bull Dog 20 ft. 2012 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 Outboard - 21 ft. 2008 at 21,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The ThunderJet Bull Dog 20 ft. 2012 at 2,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
