Sea Ray 270 Sundeck 2005 vs Sea Ray 300 Select EX 2008 — Same Brand, Different Boat

The Sea Ray 270 Sundeck 2005 vs Sea Ray 300 Select EX 2008 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.

The Sea Ray 300 Select EX 2008 tops out at 320 hp. Engine specs for the Sea Ray 270 Sundeck 2005 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Sea Ray 270 Sundeck 2005 carries 85 gallons versus 13 gallons in the Sea Ray 300 Select EX 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 8 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 300 Select EX 2008 at 29,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Sea Ray 270 Sundeck 2005 at 26,0 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.
