The Sea Ray 520 Sedan Bridge 2012 vs Sea Ray SPX 210 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 520 Sedan Bridge 2012 measures 52,3 feet overall (2012), giving it roughly 28,4 additional feet of deck space compared to the Sea Ray SPX 210 Outboard 2023 at 23,9 feet (2023). Weight tells a clearer story for trailering families: the Sea Ray SPX 210 Outboard 2023 tips the scales at 3 020 lbs — 2 978 lbs less than the Sea Ray 520 Sedan Bridge 2012 at 42 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 764 hp, the Sea Ray 520 Sedan Bridge 2012 has a 614-hp advantage over the Sea Ray SPX 210 Outboard 2023's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 5 gal and 4 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Sea Ray 520 Sedan Bridge 2012 is rated for 15 passengers, while the Sea Ray SPX 210 Outboard 2023 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 520 Sedan Bridge 2012 could be the deciding factor.
