When two boats share the same hull type — in this case both the Stamas 326 Tarpon Outboard 2012 and the Stamas 340 Express Outboard 2006 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 340 Express Outboard 2006 measures 41,0 feet overall (2006), giving it roughly 8,5 additional feet of deck space compared to the Stamas 326 Tarpon Outboard 2012 at 32,5 feet (2012). Weight tells a clearer story for trailering families: the Stamas 326 Tarpon Outboard 2012 tips the scales at 955 lbs — 817 lbs more than the Stamas 340 Express Outboard 2006 at 138 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 326 Tarpon Outboard 2012 carries a rated maximum of 600 hp. Engine data for the Stamas 340 Express Outboard 2006 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Stamas 340 Express Outboard 2006 carries 35 gallons versus 4 gallons in the Stamas 326 Tarpon Outboard 2012. 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 340 Express Outboard 2006 is rated for 12 passengers, while the Stamas 326 Tarpon Outboard 2012 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Stamas 340 Express Outboard 2006 could be the deciding factor.
