Sea Ray 350 Sundancer 2013 vs Sea Ray SLX 310 Outboard 2023 — Same Brand, Different Boat

The Sea Ray 350 Sundancer 2013 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.

Both boats share a closely matched power ceiling — 300 hp for the Sea Ray 350 Sundancer 2013 and 300 hp for the Sea Ray SLX 310 Outboard 2023. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Sea Ray 350 Sundancer 2013 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 2013 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 2013 vs Sea Ray SLX 310 Outboard 2023 — Common Questions

Which is the larger boat — the Sea Ray 350 Sundancer 2013 or the Sea Ray SLX 310 Outboard 2023?
The Sea Ray 350 Sundancer 2013 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.
How many people can each boat hold?
The Sea Ray 350 Sundancer 2013 is Coast Guard rated for 10 passengers, while the Sea Ray SLX 310 Outboard 2023 is certified for 10.

Which boat is wider, and does it affect trailering?
The Sea Ray 350 Sundancer 2013 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.

The Sea Ray 350 Sundancer 2013 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 2013 and Sea Ray SLX 310 Outboard 2023 from the same manufacturer?
Yes — both the Sea Ray 350 Sundancer 2013 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.
