The Allison XB-21 ProSport Bass 2012 tops out at 510 hp. Engine specs for the Allison XB-21 BasSport 2+2 Tournament Bass 2010 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Allison XB-21 ProSport Bass 2012 carries 36 gallons versus 3 gallons in the Allison XB-21 BasSport 2+2 Tournament Bass 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Allison XB-21 ProSport Bass 2012 is rated for 6 passengers, while the Allison XB-21 BasSport 2+2 Tournament Bass 2010 caps at 4.

Bottom line: Choose the Allison XB-21 ProSport Bass 2012 if your priority is putting more people on the water — it handles 6 passengers and at 21,2 ft it has the deck room to back that rating up comfortably. The Allison XB-21 BasSport 2+2 Tournament Bass 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
