Detailed Evaluation & Buyer Recommendation
Sylvan 1700 Avenger DC 2005 vs Sylvan Mirage Signature 8520 RE 2008 — Same Brand, Different Boat
The Sylvan 1700 Avenger DC 2005 vs Sylvan Mirage Signature 8520 RE 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 135 hp, the Sylvan 1700 Avenger DC 2005 has a 45-hp advantage over the Sylvan Mirage Signature 8520 RE 2008's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sylvan 1700 Avenger DC 2005 carries 31 gallons versus 24 gallons in the Sylvan Mirage Signature 8520 RE 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Sylvan Mirage Signature 8520 RE 2008 is rated for 12 passengers, while the Sylvan 1700 Avenger DC 2005 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sylvan Mirage Signature 8520 RE 2008 could be the deciding factor.
Bottom line: Choose the Sylvan Mirage Signature 8520 RE 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 Avenger DC 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
