Chaparral 21 SSI

BoatVerdict market snapshot

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 31 sellers are asking, which is the number you are actually negotiating against.

The BoatVerdict take

• BoatVerdict listing data

  Pricing is tight: the middle half of listings sits between $48,000 and $73,500, only a 1.5x spread. A boat asking well outside that band needs a reason, and "it is loaded" is usually not enough of one.

• BoatVerdict listing data

  Between the 2020 ($26,500 median) and the 2027 ($75,000 median) asking prices fall about 14% a year. The steepest part of that curve is behind any boat more than five years old, which is where the value sits.

• Recall (USCG/CPSC)

  3 federal recall campaigns on file touch this builder. Check the specific hull against the recall list below before you put money down; remedies are free but only if the work was actually done.

Each point is tagged with the evidence behind it. Nothing here is a claim we cannot trace back to a counted listing, a federal record, or a named analyst judgement.

Chaparral 21 SSI prices by model year

18 distinct boats, listed now or since taken down, re-posts counted once. Years with fewer than 3 boats show a count only. Asking prices, not sale prices.

What a used Chaparral 21 SSI is worth

We have seen 18 distinct Chaparral 21 SSI boats for sale between Jun 14, 2026 and Nov 14, 2026, model years 2020 to 2027, in 9 states. The median ask is $57,500 and half of all asks sit between $50,000 and $74,000. Asking prices fall about 10.1% for each year of age (41% over five years), measured on these 18 boats and steadied with the 9.3% rate we measure for the class.

Of the 12 listed now, 25% have been for sale for 60 days or more, counting re-posts as one boat. A boat that has sat that long usually has room to negotiate.

Engines: median 150 hp across 3 boats that stated it. Engine brands named: Yamaha 1, Mercury 1.

Recalls affecting Chaparral

3 federal recall campaigns on file. Recalls are issued against hull-identification ranges, so a campaign listed here may or may not cover the specific boat you are looking at — check the HIN. Remedies are free from the builder, but only if the work was actually performed, and there is no central database that proves it was.

Engines we actually see on the 21 SSI

• MerCruiser sterndrive (gas, 4.5L–6.2L) 1 listing · 3% of our sample · median 45 hp

  The most common inboard/outboard in US bowriders and cruisers. The engine itself (GM-based) is reliable; the maintenance burden is the drive and exhaust. Bellows, gimbal bearing, U-joints, and — in any saltwater service — exhaust manifolds and risers are the recurring costs.

  Service reality: Bellows/gimbal every ~5 years; manifolds/risers every ~6–8 years (or 3–4 in salt) at $2.5–4K. Pull the drive on inspection — deferred drive service is the classic hidden cost.

  Full MerCruiser sterndrive (gas, 4.5L–6.2L) reliability profile →

• Yamaha 4-stroke outboard (F70–F300) 1 listing · 3% of our sample · median 150 hp

  The benchmark for outboard reliability and resale. F150 and F300 routinely run 2,000+ hours with routine service. Top-tier buyer trust — a Yamaha-powered hull sells faster than the same boat on any other brand.

  Service reality: 100-hour service intervals; 10-year/1,000-hour anode and water-pump attention. Saltwater units: check the bus bar and starter solenoid behind the powerhead for corrosion.

What to inspect on a used Chaparral 21 SSI

1. MerCruiser sterndrive (gas, 4.5L–6.2L): Bellows/gimbal every ~5 years; manifolds/risers every ~6–8 years (or 3–4 in salt) at $2.5–4K. Pull the drive on inspection — deferred drive service is the classic hidden cost. Seen on 1 of the 31 21 SSI listings we track (typically 45 hp on this model).
2. Get the hour meter reading and divide by the boat's age. Above 100 hours a year is heavy use for a MerCruiser sterndrive (gas, 4.5L–6.2L). Threshold from BoatVerdict's engine-family profile for MerCruiser sterndrive (gas, 4.5L–6.2L).
3. Yamaha 4-stroke outboard (F70–F300): 100-hour service intervals; 10-year/1,000-hour anode and water-pump attention. Saltwater units: check the bus bar and starter solenoid behind the powerhead for corrosion. Seen on 1 of the 31 21 SSI listings we track (typically 150 hp on this model).
4. Get the hour meter reading and divide by the boat's age. Above 150 hours a year is heavy use for a Yamaha 4-stroke outboard (F70–F300). Threshold from BoatVerdict's engine-family profile for Yamaha 4-stroke outboard (F70–F300).
5. Assume saltwater service unless the seller can prove otherwise: pull the engine cowling and look at the powerhead, check trim-cylinder rams for pitting, and open the battery and fuse boxes for green corrosion. 79% of the listings we observed for this model are in coastal states.

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 SSI listings. It is not a generic pre-purchase checklist, and it does not replace a surveyor.
