The Sea Ray 300 Select EX 2008 vs Sea Ray SLX 310 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.

Both boats share a closely matched power ceiling — 320 hp for the Sea Ray 300 Select EX 2008 and 300 hp for the Sea Ray SLX 310 Outboard 2023. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Sea Ray SLX 310 Outboard 2023 carries 158 gallons versus 13 gallons in the Sea Ray 300 Select EX 2008. 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 SLX 310 Outboard 2023 is rated for 10 passengers, while the Sea Ray 300 Select EX 2008 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray SLX 310 Outboard 2023 could be the deciding factor.
