On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The ThunderJet Alexis - 21 ft. 2008 is rated for 8 passengers, while the ThunderJet Maxim Classic Outboard - 23 ft. 2008 caps at 7.

Bottom line: Choose the ThunderJet Alexis - 21 ft. 2008 if your priority is putting more people on the water — it handles 8 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The ThunderJet Maxim Classic Outboard - 23 ft. 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
