Detailed Evaluation & Buyer Recommendation
Sea Ray 310 Sundancer 2011 vs Sea Ray SLX 350 Outboard 2022 — Same Brand, Different Boat
The Sea Ray 310 Sundancer 2011 vs Sea Ray SLX 350 Outboard 2022 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.
Size is the most obvious dividing line here. The Sea Ray SLX 350 Outboard 2022 measures 34,7 feet overall (2022), giving it roughly 3,7 additional feet of deck space compared to the Sea Ray 310 Sundancer 2011 at 31,0 feet (2011). Weight tells a clearer story for trailering families: the Sea Ray SLX 350 Outboard 2022 tips the scales at 12 060 lbs — 10 897 lbs less than the Sea Ray 310 Sundancer 2011 at 1 163 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 350 hp, the Sea Ray SLX 350 Outboard 2022 has a 50-hp advantage over the Sea Ray 310 Sundancer 2011's 300-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sea Ray SLX 350 Outboard 2022 carries 177 gallons versus 125 gallons in the Sea Ray 310 Sundancer 2011. 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 Sea Ray SLX 350 Outboard 2022 is rated for 10 passengers, while the Sea Ray 310 Sundancer 2011 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray SLX 350 Outboard 2022 could be the deciding factor.
Bottom line: Choose the Sea Ray SLX 350 Outboard 2022 if your priority is putting more people on the water — it handles 10 passengers and at 34,7 ft it has the deck room to back that rating up comfortably. The Sea Ray 310 Sundancer 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
