The Sea Ray 240 Sundancer 2006 vs Sea Ray SDX 290 Outboard 2022 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 SDX 290 Outboard 2022 measures 31,2 feet overall (2022), giving it roughly 7,2 additional feet of deck space compared to the Sea Ray 240 Sundancer 2006 at 24,0 feet (2006). Weight tells a clearer story for trailering families: the Sea Ray SDX 290 Outboard 2022 tips the scales at 7 030 lbs — 1 437 lbs less than the Sea Ray 240 Sundancer 2006 at 5 593 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 320 hp, the Sea Ray 240 Sundancer 2006 has a 120-hp advantage over the Sea Ray SDX 290 Outboard 2022's 200-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 240 Sundancer 2006 carries 75 gallons versus 13 gallons in the Sea Ray SDX 290 Outboard 2022. 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 SDX 290 Outboard 2022 is rated for 9 passengers, while the Sea Ray 240 Sundancer 2006 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray SDX 290 Outboard 2022 could be the deciding factor.
