Sea Ray SDX 270 Outboard 2018 vs Sea Ray Sunsport 290 2003 — Same Brand, Different Boat

The Sea Ray SDX 270 Outboard 2018 vs Sea Ray Sunsport 290 2003 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 power gap is worth calling out. Rated to 300 hp, the Sea Ray Sunsport 290 2003 has a 50-hp advantage over the Sea Ray SDX 270 Outboard 2018's 250-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 SDX 270 Outboard 2018 carries 65 gallons versus 13 gallons in the Sea Ray Sunsport 290 2003. 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: Performance buyers should lean toward the Sea Ray Sunsport 290 2003 and its 300-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Sea Ray SDX 270 Outboard 2018 with its 250-hp rating is the more economical daily driver.

The Sea Ray Sunsport 290 2003 measures 118" wide, compared to 103" for the Sea Ray SDX 270 Outboard 2018. 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.
