When two boats share the same hull type — in this case both the Stamas 320 Express Outboard 2011 and the Stamas Predator 308 2010 are modified vee designs with fiberglass 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?

Size is the most obvious dividing line here. The Stamas 320 Express Outboard 2011 measures 34,4 feet overall (2011), giving it roughly 3,8 additional feet of deck space compared to the Stamas Predator 308 2010 at 30,7 feet (2010). Weight tells a clearer story for trailering families: the Stamas Predator 308 2010 tips the scales at 825 lbs — 698 lbs less than the Stamas 320 Express Outboard 2011 at 127 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The Stamas Predator 308 2010 tops out at 300 hp. Engine specs for the Stamas 320 Express Outboard 2011 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Stamas 320 Express Outboard 2011 carries 316 gallons versus 275 gallons in the Stamas Predator 308 2010. 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 Stamas 320 Express Outboard 2011 is rated for 10 passengers, while the Stamas Predator 308 2010 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Stamas 320 Express Outboard 2011 could be the deciding factor.
