Sea Ray 350 Sundancer 2011 vs Sea Ray SLX 310 Outboard 2023 — Same Brand, Different Boat

The Sea Ray 350 Sundancer 2011 vs Sea Ray SLX 310 Outboard 2023 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.

On paper these two are close siblings in the size department — Sea Ray 350 Sundancer 2011 at 35,5 ft versus Sea Ray SLX 310 Outboard 2023 at 33,1 ft. Weight tells a clearer story for trailering families: the Sea Ray SLX 310 Outboard 2023 tips the scales at 10 335 lbs — 10 181 lbs less than the Sea Ray 350 Sundancer 2011 at 154 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 375 hp, the Sea Ray 350 Sundancer 2011 has a 75-hp advantage over the Sea Ray SLX 310 Outboard 2023'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 350 Sundancer 2011 carries 225 gallons versus 158 gallons in the Sea Ray SLX 310 Outboard 2023. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 10 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Sea Ray 350 Sundancer 2011 at 35,5 ft is the right call if deck space, comfort, and entertaining are top of your list. The Sea Ray SLX 310 Outboard 2023 at 33,1 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.

Sea Ray 350 Sundancer 2011 vs Sea Ray SLX 310 Outboard 2023 — Common Questions

Which is the larger boat — the Sea Ray 350 Sundancer 2011 or the Sea Ray SLX 310 Outboard 2023?
The Sea Ray 350 Sundancer 2011 is the longer of the two at 35,5 feet overall. The Sea Ray SLX 310 Outboard 2023 comes in at 33,1 feet, making it roughly 2,4 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Ray 350 Sundancer 2011 or the Sea Ray SLX 310 Outboard 2023?
For trailering, the Sea Ray 350 Sundancer 2011 has the edge at 154 lbs dry weight versus 10 335 lbs for the Sea Ray SLX 310 Outboard 2023. 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 Sea Ray 350 Sundancer 2011 is rated to a maximum of 375 hp, giving it the larger power ceiling. The Sea Ray SLX 310 Outboard 2023 tops out at 300 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 Sea Ray 350 Sundancer 2011 is Coast Guard rated for 10 passengers, while the Sea Ray SLX 310 Outboard 2023 is certified for 10. 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 is wider, and does it affect trailering?
The Sea Ray 350 Sundancer 2011 measures 138" wide, compared to 122" for the Sea Ray SLX 310 Outboard 2023. 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.
Which boat has the larger fuel tank — the Sea Ray 350 Sundancer 2011 or the Sea Ray SLX 310 Outboard 2023?
The Sea Ray 350 Sundancer 2011 has the bigger tank at 225 gallons, versus 158 gallons on the Sea Ray SLX 310 Outboard 2023. That 67-gallon difference translates to roughly 201–335 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sea Ray 350 Sundancer 2011 and Sea Ray SLX 310 Outboard 2023 from the same manufacturer?
Yes — both the Sea Ray 350 Sundancer 2011 and the Sea Ray SLX 310 Outboard 2023 are built by Sea Ray. 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.
