South Bay 25 Sport SL DC Twin 2022 vs South Bay 520FC 2009 — Same Brand, Different Boat
The South Bay 25 Sport SL DC Twin 2022 vs South Bay 520FC 2009 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 South Bay 520FC 2009 tops out at 90 hp. Engine specs for the South Bay 25 Sport SL DC Twin 2022 aren't listed — confirm with a dealer before selecting an outboard.
For family outings this is probably the sharpest distinction between the two. The South Bay 520FC 2009 is rated for 11 passengers, while the South Bay 25 Sport SL DC Twin 2022 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the South Bay 520FC 2009 could be the deciding factor.
Bottom line: Choose the South Bay 520FC 2009 if your priority is putting more people on the water — it handles 11 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The South Bay 25 Sport SL DC Twin 2022 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.
