Sea Ray Express Cruiser 390 1990 vs Sea Ray SLX 250 2022 — Same Brand, Different Boat

The Sea Ray Express Cruiser 390 1990 vs Sea Ray SLX 250 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 Express Cruiser 390 1990 measures 42,0 feet overall (1990), giving it roughly 16,4 additional feet of deck space compared to the Sea Ray SLX 250 2022 at 25,6 feet (2022). Weight tells a clearer story for trailering families: the Sea Ray Express Cruiser 390 1990 tips the scales at 16 400 lbs — 10 600 lbs more than the Sea Ray SLX 250 2022 at 5 800 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 Express Cruiser 390 1990 has a 70-hp advantage over the Sea Ray SLX 250 2022's 300-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 SLX 250 2022 carries 75 gallons versus 3 gallons in the Sea Ray Express Cruiser 390 1990. 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 Express Cruiser 390 1990 is rated for 12 passengers, while the Sea Ray SLX 250 2022 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 Express Cruiser 390 1990 could be the deciding factor.

Bottom line: Choose the Sea Ray Express Cruiser 390 1990 if your priority is putting more people on the water — it handles 12 passengers and at 42,0 ft it has the deck room to back that rating up comfortably. The Sea Ray SLX 250 2022 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.

Sea Ray Express Cruiser 390 1990 vs Sea Ray SLX 250 2022 — Common Questions

Which is the larger boat — the Sea Ray Express Cruiser 390 1990 or the Sea Ray SLX 250 2022?
The Sea Ray Express Cruiser 390 1990 is the longer of the two at 42,0 feet overall. The Sea Ray SLX 250 2022 comes in at 25,6 feet, making it roughly 16,4 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Ray Express Cruiser 390 1990 or the Sea Ray SLX 250 2022?
For trailering, the Sea Ray SLX 250 2022 has the edge at 5 800 lbs dry weight versus 16 400 lbs for the Sea Ray Express Cruiser 390 1990. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Sea Ray Express Cruiser 390 1990 is rated to a maximum of 370 hp, giving it the larger power ceiling. The Sea Ray SLX 250 2022 tops out at 300 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Sea Ray Express Cruiser 390 1990 is Coast Guard rated for 12 passengers, while the Sea Ray SLX 250 2022 is certified for 7. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Sea Ray Express Cruiser 390 1990 measures 157" wide, compared to 103" for the Sea Ray SLX 250 2022. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Sea Ray Express Cruiser 390 1990 or the Sea Ray SLX 250 2022?
The Sea Ray SLX 250 2022 has the bigger tank at 75 gallons, versus 3 gallons on the Sea Ray Express Cruiser 390 1990. That 72-gallon difference translates to roughly 216–360 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sea Ray Express Cruiser 390 1990 and Sea Ray SLX 250 2022 from the same manufacturer?
Yes — both the Sea Ray Express Cruiser 390 1990 and the Sea Ray SLX 250 2022 are built by Sea Ray. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
