The Stamas 290 Tarpon Outboard 2006 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 290 Tarpon Outboard 2006's 500-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 302 gal and 302 gal — so range won't be a tiebreaker here.

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.
