When two boats share the same hull type — in this case both the ThunderJet Alexis OB Offshore 2010 and the ThunderJet Envoy - Northern Edition 2010 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 Envoy - Northern Edition 2010 tops out at 25 hp. Engine specs for the ThunderJet Alexis OB Offshore 2010 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the ThunderJet Envoy - Northern Edition 2010 carries 48 gallons versus 5 gallons in the ThunderJet Alexis OB Offshore 2010.

For family outings this is probably the sharpest distinction between the two. The ThunderJet Alexis OB Offshore 2010 is rated for 6 passengers, while the ThunderJet Envoy - Northern Edition 2010 caps at 5.

The ThunderJet Envoy - Northern Edition 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
