Sylvan Expedition Sport 1700 DC 2012 vs Sylvan Mirage 8520 C 2008 — Same Brand, Different Boat

Matching a modified vee Sylvan Expedition Sport 1700 DC 2012 against a pontoon Sylvan Mirage 8520 C 2008 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The Sylvan Expedition Sport 1700 DC 2012 measures 17,1 feet overall (2012), giving it roughly 15,1 additional feet of deck space compared to the Sylvan Mirage 8520 C 2008 at 2,0 feet (2008). Weight tells a clearer story for trailering families: the Sylvan Mirage 8520 C 2008 tips the scales at 1 875 lbs — 550 lbs less than the Sylvan Expedition Sport 1700 DC 2012 at 1 325 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 140 hp, the Sylvan Expedition Sport 1700 DC 2012 has a 50-hp advantage over the Sylvan Mirage 8520 C 2008's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 24 gal and 24 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Sylvan Mirage 8520 C 2008 is rated for 12 passengers, while the Sylvan Expedition Sport 1700 DC 2012 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sylvan Mirage 8520 C 2008 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Sylvan Expedition Sport 1700 DC 2012 comes in at 10 lbs per hp versus 21 lbs per hp for the Sylvan Mirage 8520 C 2008. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

Bottom line: Choose the Sylvan Mirage 8520 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 Expedition Sport 1700 DC 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.

Sylvan Expedition Sport 1700 DC 2012 vs Sylvan Mirage 8520 C 2008 — Common Questions

Which is the larger boat — the Sylvan Expedition Sport 1700 DC 2012 or the Sylvan Mirage 8520 C 2008?
The Sylvan Expedition Sport 1700 DC 2012 is the longer of the two at 17,1 feet overall. The Sylvan Mirage 8520 C 2008 comes in at 2,0 feet, making it roughly 15,1 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sylvan Expedition Sport 1700 DC 2012 or the Sylvan Mirage 8520 C 2008?
For trailering, the Sylvan Expedition Sport 1700 DC 2012 has the edge at 1 325 lbs dry weight versus 1 875 lbs for the Sylvan Mirage 8520 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 Expedition Sport 1700 DC 2012 is rated to a maximum of 140 hp, giving it the larger power ceiling. The Sylvan Mirage 8520 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 Expedition Sport 1700 DC 2012 is Coast Guard rated for 6 passengers, while the Sylvan Mirage 8520 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 has the better power-to-weight ratio?
The Sylvan Expedition Sport 1700 DC 2012 has a better power-to-weight ratio at 10 lbs per hp compared to 21 lbs per hp for the Sylvan Mirage 8520 C 2008. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Which boat is wider, and does it affect trailering?
The Sylvan Mirage 8520 C 2008 measures 102" wide, compared to 91" for the Sylvan Expedition Sport 1700 DC 2012. 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 Sylvan Expedition Sport 1700 DC 2012 and Sylvan Mirage 8520 C 2008?
Both boats carry similar fuel loads — 24 gallons and 24 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Sylvan Expedition Sport 1700 DC 2012 and Sylvan Mirage 8520 C 2008 from the same manufacturer?
Yes — both the Sylvan Expedition Sport 1700 DC 2012 and the Sylvan Mirage 8520 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.
