The Stamas 310 Tarpon Outboard 2007 vs Stamas Yacht 317 Tarpon 2017 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

The power gap is worth calling out. Rated to 600 hp, the Stamas Yacht 317 Tarpon 2017 has a 100-hp advantage over the Stamas 310 Tarpon Outboard 2007's 500-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Stamas Yacht 317 Tarpon 2017 carries 302 gallons versus 4 gallons in the Stamas 310 Tarpon Outboard 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 9 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
