The Starcraft Marine 191 IO 2008 vs Starcraft Marine C-Star 166 SC 2006 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.

On paper these two are close siblings in the size department — Starcraft Marine 191 IO 2008 at 19,0 ft versus Starcraft Marine C-Star 166 SC 2006 at 16,0 ft.

Rated to 125 hp, the Starcraft Marine C-Star 166 SC 2006 has a 122-hp advantage over the Starcraft Marine 191 IO 2008's 3-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 34 gal and 32 gal — so range won't be a tiebreaker here.
