BoatVerdict market snapshot
What "time listed" is and is not. We count from the day the seller posted the ad to the sweep that found it gone. An ad can end because the boat sold, because the seller gave up, or because the classifieds site expired the post on its own schedule. So read 25 days as how long a 21 Party Barge sits for sale, not as a time-to-sale. Nobody in this market can give you a real one: US used-boat sales are not publicly recorded. Ads that were already gone the first time we could see a whole regional board are left out of this figure, because we know they left but not when.
These are asking prices. No free or public source publishes US used-boat transaction prices, so nobody — us included — can honestly show you what these boats sold for. What we can show you is what 25 sellers are asking, which is the number you are actually negotiating against.
25 priced listings across 10 states. Enough for a range, not enough to be precise about any single year.
Method: Asking prices from active listings, de-duplicated so a re-posted boat counts once (58 raw listings collapsed to 25 distinct boats). Quartiles, not averages, so one outlier cannot move the band. Rounded to $500.
Coverage: Model years 1992–2011, 10 states, 13 metro areas. New-boat listings excluded.

The 8 most recently seen of 8 distinct boats. These are asking prices, not sale prices: no free source publishes US used-boat sale prices. A boat re-posted several times counts once, at its latest ask. "Taken down" means the ad disappeared; that can be a sale, a seller who gave up, or an expired post.
Sun Tracker recalls and accident record
Of 207Sun Tracker boats in USCG accident records: fire or explosion 6%, flooding or swamping 2%, capsizing 2%, total loss 2%, at least one death 17%.

These numbers are for the builder, not this model. Check the specific hull with a HIN lookup for recalls and reported accidents.
Engines we actually see on the 21 Party Barge
- Mercury Verado / V8 FourStroke (250–400)
Modern Mercury V8/V10 FourStroke and supercharged Verado are strong, smooth, and well-supported, a clear step up from the OptiMax era. Slightly behind Yamaha on resale trust but closing fast, and often better integrated (joystick, digital throttle).
Service reality: 100-hour service; supercharged Verado adds the supercharger oil interval. Check for corroded battery cables and the SmartCraft harness on saltwater boats.
Full Mercury Verado / V8 FourStroke (250–400) reliability profile →
- Honda 4-stroke outboard
Among the most reliable outboards made — automotive-grade Honda 4-stroke engineering. Heavier than rivals and a smaller marine dealer network, but mechanically a top-tier, long-life choice.
Service reality: Timing-belt models: verify replacement interval was honored. 100-hour service; confirm dealer access for the buyer's region.
- Carbureted 2-stroke outboard (legacy)
Pre-DI carbureted 2-strokes (and Evinrude/Johnson, now an orphaned brand for parts/service). Simple and cheap to buy, but thirsty, smoky, and a resale anchor. An older 2-stroke is the single biggest reason a hull sits unsold.
Service reality: Compression-test every cylinder; expect carb work. On any Evinrude/Johnson, confirm local parts and service availability before buying.

- On the older hulls, core moisture is the deal-breaker: sound the transom and the deck with a plastic mallet, and treat any soft or dull-sounding area as a survey-stopper rather than a bargaining chip. We observe listings back to 1992, so boats over 34 years old are actively traded in this model.
This list is specific to this model: analyst items for the hull, plus items driven by the engines and the regions we actually observe on 21 Party Barge listings. It is not a generic pre-purchase checklist, and it does not replace a surveyor.
What a 21 Party Barge costs to own
$1,500 – $4,000 per year
- 21 ft hull, the median observed length for this model
- Freshwater berth, based on where most listings we see are located (AZ)
- Includes insurance, storage, routine service, fuel at moderate seasonal use, and a reserve for wear items

This is a modelled band, not observed spend. Real cost swings hard on where you keep the boat and how much you use it.
Method: The same ownership-cost model BoatVerdict's paid Deal Report uses: boat class and length set the base band, then saltwater berth and size adjust it.
