Detailed Evaluation & Buyer Recommendation
ThunderJet Alexis OB 2009 vs ThunderJet Havasu 2008 — A Close Look at Two Modified Vees
When two boats share the same hull type — in this case both the ThunderJet Alexis OB 2009 and the ThunderJet Havasu 2008 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 Havasu 2008 tops out at 425 hp. Engine specs for the ThunderJet Alexis OB 2009 aren't listed — confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads — 5 gal and 5 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The ThunderJet Havasu 2008 is rated for 8 passengers, while the ThunderJet Alexis OB 2009 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the ThunderJet Havasu 2008 could be the deciding factor.
Bottom line: Choose the ThunderJet Havasu 2008 if your priority is putting more people on the water — it handles 8 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The ThunderJet Alexis OB 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
