2020 Sea Ray SLX-R 350 Outboard
The SLX-R 350 is the special edition of Sea Ray's flagship SLX bowrider, and the only version that came standard with twin Mercury Racing 450R supercharged V8 outboards. That is 900 horsepower on a 36-foot dayboat, paired with Mercury joystick piloting, Skyhook and a bow thruster, so she is as easy to park as she is quick on the water.
Servicing and antifouling has been completed in September 2026, and is showing just 94 hours on the engines; this is a great find and one that will not last long. She is finished in the SLX-R's Shadow metallic hull with a red boot stripe, white contrast-stitched upholstery and grey synthetic teak decking, and presents in excellent condition.
HELM
The helm is built around a Simrad glass bridge with twin 12" displays carrying chartplotting, sounder and Mercury engine data. A Simrad radar is mounted on the hardtop. Fusion audio runs the whole boat, with remotes at the bow and transom. Lenco trim tabs, an electric windlass with helm control and a Marinco remote spotlight complete the helm.
ENTERTAINING
This is a boat made for a day on the water. The bow seats a crowd around two teak tables, and the cockpit has a U-shaped lounge with a teak table opposite the helm. The cockpit wet bar carries a sink, a Kenyon electric grill and an Isotherm stainless drawer fridge. An aft-facing transom lounge looks over the swim platform, which runs either side of the outboards with a boarding ladder and cockpit shower. The hardtop has an electric extendable aft awning.
BELOW DECK
The Port Hideaway cabin has a convertible lounge that sleeps two and a flat-screen TV. A separate head sits under the starboard helm with an electric toilet and vanity sink. 15 amp shore power.
