The Sea Ray 390 Sedan Bridge 2010 vs Sea Ray SPX 190 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 390 Sedan Bridge 2010 measures 38,3 feet overall (2010), giving it roughly 16,4 additional feet of deck space compared to the Sea Ray SPX 190 Outboard 2023 at 21,9 feet (2023). Weight tells a clearer story for trailering families: the Sea Ray SPX 190 Outboard 2023 tips the scales at 3 026 lbs — 3 004 lbs less than the Sea Ray 390 Sedan Bridge 2010 at 22 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 370 hp, the Sea Ray 390 Sedan Bridge 2010 has a 255-hp advantage over the Sea Ray SPX 190 Outboard 2023's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 3 gal and 3 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Sea Ray 390 Sedan Bridge 2010 is rated for 11 passengers, while the Sea Ray SPX 190 Outboard 2023 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray 390 Sedan Bridge 2010 could be the deciding factor.
