Both the Stamas 270 Tarpon Outboard 2007 and the Stamas 310 Tarpon 2010 are modified-V designs, both built in fibreglass, so 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 310 Tarpon 2010 measures 32,5 feet overall (2010), giving it roughly 4,5 additional feet of deck space compared to the Stamas 270 Tarpon Outboard 2007 at 28,0 feet (2007). Weight tells a clearer story for trailering families: the Stamas 310 Tarpon 2010 tips the scales at 9 700 lbs - 4 500 lbs less than the Stamas 270 Tarpon Outboard 2007 at 5 200 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 270 Tarpon Outboard 2007 carries a rated maximum of 450 hp. Engine data for the Stamas 310 Tarpon 2010 wasn't available in our records - check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Stamas 310 Tarpon 2010 carries 225 gallons versus 220 gallons in the Stamas 270 Tarpon Outboard 2007. 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 310 Tarpon 2010 is rated for 9 passengers, while the Stamas 270 Tarpon Outboard 2007 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Stamas 310 Tarpon 2010 could be the deciding factor.
Bottom line: Choose the Stamas 310 Tarpon 2010 if your priority is putting more people on the water - it handles 9 passengers and at 32,5 ft it has the deck room to back that rating up comfortably. The Stamas 270 Tarpon Outboard 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
