Sea Ray 270 Select EX 2005 vs Sea Ray SLX 310 Outboard 2023 — Same Brand, Different Boat

The Sea Ray 270 Select EX 2005 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.

Size is the most obvious dividing line here. The Sea Ray SLX 310 Outboard 2023 measures 33,1 feet overall (2023), giving it roughly 5,1 additional feet of deck space compared to the Sea Ray 270 Select EX 2005 at 28,0 feet (2005). Weight tells a clearer story for trailering families: the Sea Ray SLX 310 Outboard 2023 tips the scales at 10 335 lbs — 4 780 lbs less than the Sea Ray 270 Select EX 2005 at 5 555 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 Sea Ray SLX 310 Outboard 2023 tops out at 300 hp. Engine specs for the Sea Ray 270 Select EX 2005 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Sea Ray SLX 310 Outboard 2023 carries 158 gallons versus 94 gallons in the Sea Ray 270 Select EX 2005. 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 270 Select EX 2005 caps at 8. 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.

Bottom line: Choose the Sea Ray SLX 310 Outboard 2023 if your priority is putting more people on the water — it handles 10 passengers and at 33,1 ft it has the deck room to back that rating up comfortably. The Sea Ray 270 Select EX 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.

For trailering, the Sea Ray 270 Select EX 2005 has the edge at 5 555 lbs dry weight versus 10 335 lbs for the Sea Ray SLX 310 Outboard 2023.
