Starcraft Marine C-Star 186 DC 2004 vs Starcraft Marine Islander 191 2004 — Same Brand, Different Boat

The Starcraft Marine C-Star 186 DC 2004 vs Starcraft Marine Islander 191 2004 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 135 hp, the Starcraft Marine Islander 191 2004 has a 120-hp advantage over the Starcraft Marine C-Star 186 DC 2004's 15-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 32 gal and 34 gal — so range won't be a tiebreaker here.

Both boats are rated for 8 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.

Bottom line: Performance buyers should lean toward the Starcraft Marine Islander 191 2004 and its 135-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Starcraft Marine C-Star 186 DC 2004 with its 15-hp rating is the more economical daily driver.

Starcraft Marine C-Star 186 DC 2004 vs Starcraft Marine Islander 191 2004 — Common Questions

Which is easier to trailer — the Starcraft Marine C-Star 186 DC 2004 or the Starcraft Marine Islander 191 2004?
For trailering, the Starcraft Marine C-Star 186 DC 2004 has the edge at 1 265 lbs dry weight versus 1 525 lbs for the Starcraft Marine Islander 191 2004. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Starcraft Marine Islander 191 2004 is rated to a maximum of 135 hp, giving it the larger power ceiling. The Starcraft Marine C-Star 186 DC 2004 tops out at 15 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Starcraft Marine C-Star 186 DC 2004 is Coast Guard rated for 8 passengers, while the Starcraft Marine Islander 191 2004 is certified for 8. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Starcraft Marine Islander 191 2004 measures 96" wide, compared to 92" for the Starcraft Marine C-Star 186 DC 2004. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
How do the fuel tanks compare on the Starcraft Marine C-Star 186 DC 2004 and Starcraft Marine Islander 191 2004?
Both boats carry similar fuel loads — 32 gallons and 34 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Starcraft Marine C-Star 186 DC 2004 and Starcraft Marine Islander 191 2004 from the same manufacturer?
Yes — both the Starcraft Marine C-Star 186 DC 2004 and the Starcraft Marine Islander 191 2004 are built by Starcraft Marine. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
