When two boats share the same hull type — in this case both the Stamas 267 Tarpon Outboard 2012 and the Stamas 317 Tarpon Inboard 2012 are deep 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 317 Tarpon Inboard 2012 measures 31,6 feet overall (2012), giving it roughly 5,0 additional feet of deck space compared to the Stamas 267 Tarpon Outboard 2012 at 26,6 feet (2012). At 46 lbs and 63 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The Stamas 267 Tarpon Outboard 2012 carries a rated maximum of 400 hp. Engine data for the Stamas 317 Tarpon Inboard 2012 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Stamas 267 Tarpon Outboard 2012 carries 162 gallons versus 2 gallons in the Stamas 317 Tarpon Inboard 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 317 Tarpon Inboard 2012 is rated for 10 passengers, while the Stamas 267 Tarpon Outboard 2012 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Stamas 317 Tarpon Inboard 2012 could be the deciding factor.
Bottom line: Choose the Stamas 317 Tarpon Inboard 2012 if your priority is putting more people on the water — it handles 10 passengers and at 31,6 ft it has the deck room to back that rating up comfortably. The Stamas 267 Tarpon Outboard 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
