The Sea Ray 280 Sundancer 2008 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 280 Sundancer 2008 at 31,0 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 — 9 472 lbs less than the Sea Ray 280 Sundancer 2008 at 863 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 280 Sundancer 2008 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 SLX 310 Outboard 2023 carries 158 gallons versus 1 gallons in the Sea Ray 280 Sundancer 2008. 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 310 Outboard 2023 is rated for 10 passengers, while the Sea Ray 280 Sundancer 2008 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 310 Outboard 2023 could be the deciding factor.
