Detailed Evaluation & Buyer Recommendation
Sylvan Expedition Sport 1700 DC 2007 vs Sylvan Mirage Fish 820 4-PT 2012 — Same Brand, Different Boat
Matching a modified vee Sylvan Expedition Sport 1700 DC 2007 against a pontoon Sylvan Mirage Fish 820 4-PT 2012 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.
The power gap is worth calling out. Rated to 135 hp, the Sylvan Expedition Sport 1700 DC 2007 has a 45-hp advantage over the Sylvan Mirage Fish 820 4-PT 2012'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 Fish 820 4-PT 2012 is rated for 6 passengers, while the Sylvan Expedition Sport 1700 DC 2007 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 Fish 820 4-PT 2012 could be the deciding factor.
Bottom line: Choose the Sylvan Mirage Fish 820 4-PT 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 Expedition Sport 1700 DC 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
