Quick Verdict
- Sterndrives keep 14,235 lb low and inboard and leave the transom clear — a full-width swim platform, plus an automated submersible swim step Sea Ray does not offer on the SLX 350 Outboard
- Six published propulsion configurations, from twin MerCruiser 6.2L at T-300 hp to twin 8.2L MAG at T-380 hp, with SeaCore closed cooling available at every step — a wider ladder than the outboard version's three
- The Port Hideaway is a genuinely air-conditioned interior space on an open 36-footer, with SeaDek flooring, filler cushions and a TV; a berth upgrade is optional, but Sea Ray publishes no berth count and no "Sleeps" row for this model
- Sea Ray publishes a 44–52 mph wide-open throttle band and a 21° deadrise, but no cruising speed, no fuel burn and no range — plan the sea trial to produce those yourself against 160 gallons
- Five-year SURPA5S+ bow-to-stern cover plus a Limited Lifetime Structural Hull/Deck warranty to the original owner; only the SLX 400 and SLX 400 Outboard are excluded from that scheme
- The trade is a calendar: bellows, gimbal bearings and drive service are annual items the outboard SLX 350 owner never sees, and in salt water SeaCore stops being optional in practice
Our Take
I will say the unfashionable thing first. Outboards have taken this segment, and in most cases I would not argue. The sterndrive SLX 350 is the case where I still would, and the argument is at the back of the boat. Nothing hangs off this transom. The swim platform runs the full width, the ladder is reachable from anywhere along it, and Sea Ray will fit an automated submersible swim step that the outboard 350 has no room for. If your afternoons end with people in the water, that is not nostalgia, it is the whole point.
The other thing this version gives you is choice. Six published propulsion configurations, from twin 6.2L MerCruisers at 300 a side up to the 8.2L MAG at 380, with SeaCore closed cooling available at every rung. If the boat lives in salt water I would treat SeaCore as part of the purchase price rather than an upgrade, and I would look hard at Dynamic Running Surface too — on a 14,235-pound hull with 21 degrees of deadrise, automatic pitch and roll control changes how the boat feels to your passengers more than another 30 horsepower a side does. Sea Ray publishes 44 to 52 mph wide open and nothing else, so the rest is yours to measure: hold your real cruise, read the flow off the VesselView screen, divide 160 gallons by it, keep ten percent back.
The honest cost is the maintenance calendar. Bellows, gimbal bearings, drive service — real, annual, and an outboard owner simply does not have them. What you get back is the longest warranty in the Sea Ray range: five years bow-to-stern under SURPA5S+ plus a Limited Lifetime Structural Hull/Deck term to the original owner, from which only the SLX 400 and 400 Outboard are excluded. One last thing, because it costs people money: this boat is 36'0" and the SLX 350 Outboard is 38'0". If a listing quotes 38 feet or 48 to 64 miles an hour, you are reading about the other one.

Frequently Asked Questions
Is the Sea Ray SLX 350 the same boat as the SLX 350 Outboard?
No, and the gap is wider than the shared model number suggests. The sterndrive SLX 350 is 36'0" and 14,235 pounds dry, drawing 37 inches with the drives down and 26 up, with a published 44 to 52 mph wide-open band. The outboard is 38'0" and 13,027 pounds dry, drawing 32 and 23 inches, with a published 48 to 64 mph band.
Sea Ray publishes identical figures for only five things: the 10'6" beam, 160 gallons of fuel, 30 gallons of water, a 27-gallon holding tank and 21 degrees of deadrise. If a listing quotes 38 feet for an SLX 350, you are reading about the other boat.
What is the Port Hideaway on the Sea Ray SLX 350?
An air-conditioned interior space on the port side of an open 36-footer. Sea Ray fits it with plush seating, filler cushions, SeaDek flooring and a TV with input ports, and offers a berth upgrade as an option. There is also a head compartment with a 27-gallon holding tank, with a macerator and seacock interlock on the option list.
What it is not is a cabin. Sea Ray publishes no berth count and no Sleeps row for this model, so treat the Hideaway as a day-extender rather than accommodation.
What engine options does Sea Ray publish for the SLX 350?
Six discrete configurations, all sterndrive. Standard is twin Mercury MerCruiser 6.2L MPI ECT on Bravo Three X drives with Joystick Piloting at 300 hp a side.
The published option list runs 6.2L Bravo Three at T-300, 6.2L Bravo Three X SeaCore at T-300, 6.2L Bravo Three X at T-350, 6.2L Bravo Three X SeaCore at T-350, 8.2L MAG ECT Bravo Three X at T-380 and 8.2L MAG ECT Bravo Three X SeaCore at T-380. Dynamic Running Surface is optional. That is a wider ladder than the outboard version's three choices, with SeaCore closed cooling available at every step.
How fast is the Sea Ray SLX 350?
Sea Ray publishes a 44 to 52 mph wide-open-throttle band and nothing else — no cruising speed, no fuel burn and no range for this model. Deadrise is 21 degrees and fuel capacity 160 gallons.
The gap is yours to fill on the sea trial. Hold your real cruising speed, read the fuel flow off the VesselView screen, divide 160 gallons by it and keep ten percent back. That is ten minutes of work and it is the only honest cruising number anyone is going to hand you on this hull.
