Sylvan 1700 Explorer SC 2004 vs Sylvan Mirage 8520 F-N-C 2008 — Same Brand, Different Boat

The Sylvan 1700 Explorer SC 2004 vs Sylvan Mirage 8520 F-N-C 2008 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 125 hp, the Sylvan 1700 Explorer SC 2004 has a 35-hp advantage over the Sylvan Mirage 8520 F-N-C 2008's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Sylvan Mirage 8520 F-N-C 2008 is rated for 12 passengers, while the Sylvan 1700 Explorer SC 2004 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sylvan Mirage 8520 F-N-C 2008 could be the deciding factor.

Bottom line: Choose the Sylvan Mirage 8520 F-N-C 2008 if your priority is putting more people on the water — it handles 12 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Sylvan 1700 Explorer SC 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.

Sylvan 1700 Explorer SC 2004 vs Sylvan Mirage 8520 F-N-C 2008 — Common Questions

Which is easier to trailer — the Sylvan 1700 Explorer SC 2004 or the Sylvan Mirage 8520 F-N-C 2008?
For trailering, the Sylvan 1700 Explorer SC 2004 has the edge at 124 lbs dry weight versus 1 875 lbs for the Sylvan Mirage 8520 F-N-C 2008. 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 Sylvan 1700 Explorer SC 2004 is rated to a maximum of 125 hp, giving it the larger power ceiling. The Sylvan Mirage 8520 F-N-C 2008 tops out at 90 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 Sylvan 1700 Explorer SC 2004 is Coast Guard rated for 7 passengers, while the Sylvan Mirage 8520 F-N-C 2008 is certified for 12. 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 Sylvan Mirage 8520 F-N-C 2008 measures 102" wide, compared to 85" for the Sylvan 1700 Explorer SC 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.
Are the Sylvan 1700 Explorer SC 2004 and Sylvan Mirage 8520 F-N-C 2008 from the same manufacturer?
Yes — both the Sylvan 1700 Explorer SC 2004 and the Sylvan Mirage 8520 F-N-C 2008 are built by Sylvan. 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.
