Detailed Evaluation & Buyer Recommendation
Sylvan 1700 Avenger SC 2004 vs Sylvan Mirage Cruise 820 CR 2012 — Same Brand, Different Boat
The Sylvan 1700 Avenger SC 2004 vs Sylvan Mirage Cruise 820 CR 2012 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 SC 2004 has a 45-hp advantage over the Sylvan Mirage Cruise 820 CR 2012'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 SC 2004 carries 31 gallons versus 3 gallons in the Sylvan Mirage Cruise 820 CR 2012. 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 Cruise 820 CR 2012 is rated for 6 passengers, while the Sylvan 1700 Avenger SC 2004 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 Cruise 820 CR 2012 could be the deciding factor.
Bottom line: Choose the Sylvan Mirage Cruise 820 CR 2012 if your priority is putting more people on the water — it handles 6 passengers and at 20,8 ft it has the deck room to back that rating up comfortably. The Sylvan 1700 Avenger SC 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
