Quick Verdict
- 34'9" and 220 gallons of fuel against the sterndrive Sundancer 320's 32'10" and 158 gallons — same model number, different hull, and this is the one built to go further between fuel docks
- Sea Ray rates the cabin at sleeps four with a fully finished head compartment, and offers cabin-only or cockpit-and-cabin air conditioning plus a gas generator to make that rating usable overnight
- Twin Mercury 350 Verado V10s with Joystick Piloting standard and twin 400 Verado V10s optional, but Sea Ray publishes no cruising speed, no wide-open throttle band and no range for this hull — every performance figure quoted for it anywhere is somebody's estimate
- Published draft is 44" trimmed down, deeper than the sterndrive Sundancer 320's 41"; trimmed up it is 32". On this pair the outboard is not automatically the shallow-water answer
- Three windshield configurations — open as standard, open coupe, or full coupe enclosure — change this boat more than any other option on the list
- Three-year SENTIN3L bow-to-stern cover plus a 10-year Limited Structural Hull/Deck warranty to the original owner: shorter bow-to-stern than the five years Sea Ray's SLX sport boats get, because Sundancers are filed as sport cruisers
Our Take
The first thing to get right on this boat is which boat you are actually looking at. Sea Ray builds two Sundancer 320s. The sterndrive is 32'10", 158 gallons, 14,000 pounds dry. This one is 34'9", 220 gallons, 14,566 pounds dry, with two Verado V10s hanging off the back. Same badge, different hull, and I have watched buyers walk into a viewing quoting one boat's length alongside the other's fuel capacity. If a listing mixes them, that tells you something about the listing.
What the outboards buy you here is the Sunday morning. No bellows, no gimbal bearing, no drive to pull — routine work happens under a cowling at standing height, and a salt-water flush is a hose fitting. What they cost you is the back of the boat: two V10s live where a clear walk-across platform would otherwise be. And there is one number that surprised me. Sea Ray publishes a 44-inch draft with the motors trimmed down on this hull, against 41 inches on the sterndrive. Outboards are usually the shallower answer. On this pair, trimmed down, they are not — so if you run thin water, plan around the 32-inch trimmed-up figure instead.
The decision I would spend the most time on is the windshield, and it is a climate decision rather than a taste one. Open, open coupe, or the full coupe enclosure — go stand at all three on a dock, in the weather you actually boat in. Then take the sea trial seriously, because Sea Ray publishes nothing at all about how fast this boat goes or how far. No cruise, no top end, no range. Hold the speed you would genuinely hold for an hour, read the fuel flow off the Mercury display, divide 220 gallons by it and keep ten percent back. That is ten minutes of work and it is the only honest performance number anyone is going to hand you on this hull.

Frequently Asked Questions
How fast is the Sea Ray Sundancer 320 Outboard?
Nobody can tell you honestly, because Sea Ray publishes nothing. The specification block for this model ends at Sleeps: Four — no cruising speed, no wide-open-throttle band, no range. Any figure quoted for it anywhere is somebody's estimate.
The silence is specific to this pair rather than the range: Sea Ray does publish wide-open bands for the SLX 350 and SLX 350 Outboard. Fill the gap on the sea trial. Hold the speed you would genuinely hold for an hour, read the fuel flow off the Mercury display, divide 220 gallons by it and keep ten percent back.
How is the Sundancer 320 Outboard different from the sterndrive Sundancer 320?
Same badge, different hull. The outboard is 34'9" against the sterndrive's 32'10", carries 220 gallons of fuel against 158, and weighs 14,566 pounds dry against 14,000. Power is twin Mercury 350 Verado V10 outboards with Joystick Piloting, where the sterndrive runs twin MerCruiser 6.2L engines on Bravo Three X drives.
Both are rated by Sea Ray at Sleeps: Four. The outboard is the one built to go further between fuel docks; the sterndrive is nearly two feet less boat to berth. A listing that mixes their figures tells you something about the listing.
Does the Sea Ray Sundancer 320 Outboard sleep four?
Yes — Sleeps: Four is Sea Ray's own published rating for this model. The cabin is built around a V-berth with a fully finished head compartment behind it, and waste goes to a 27-gallon holding tank, with a macerator and seacock interlock on the option list. Fresh water capacity is 32 gallons.
To make that rating usable overnight, Sea Ray offers cabin-only or cockpit-and-cabin air conditioning and a gas generator, plus three windshield configurations — open as standard, open coupe, or a full coupe enclosure.
Is the outboard Sundancer 320 the shallower boat?
Not with the engines trimmed down, which is the counter-intuitive part. Sea Ray publishes a 44-inch draft trimmed down for the Sundancer 320 Outboard against 41 inches for the sterndrive Sundancer 320. Trimmed up, the outboard draws 32 inches against the sterndrive's 30.
Outboards are usually the shallow-water answer. On this particular pair they are not. If you run thin water, plan around the trimmed-up figure and check it against your own channel at dead low rather than assuming the transom-hung motors buy you clearance.
