One of the finest 510 Sundancers on the market — freshwater kept from 2018 until just recently, professionally captain maintained, and owned by experienced boaters its entire life. The condition reflects it. Extensive pod and engine work completed in 2026 makes this a true turnkey boat, and the upgrades/services set it apart.

The Platform

Sea Ray's "Depart the Cave" design philosophy is executed exceptionally well on the 510 — a bright, open, climate-controlled helm and salon that keeps you connected to the water without the hassle of canvas. Sliding salon doors open fully to port, blurring the line between cockpit and interior. Hardwood walnut floors, raised ultraleather seating, and a swiveling double-wide helm seat that converts the upper salon into a social space. Below, an atrium design keeps the lower salon open and airy — galley forward, day head accessible from both the VIP and lower salon, and a master aft with split head and vanity for simultaneous use.

The Drive

Powered by Cummins QSC 8.3L 600s with Zeus pods, the 510 reaches approximately 34 knots at WOT and handles with precision. The Zeus system fully articulates — no propeller-to-rudder lag, just immediate response, tight turning radius, and a sport-boat feel. In hard turns the boat banks confidently while the hardtop skylights keep the horizon in view. Automatic trim tabs, BoatMate wireless joystick, Skyhook, and autopilot round out one of the most capable docking and maneuvering systems in the class.
