Key West 1720

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 32 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 $10,000 and $16,000, only a 1.6x spread. A boat asking well outside that band needs a reason, and "it is loaded" is usually not enough of one.

• BoatVerdict listing data

  Supply is national: we saw listings in 15 states. You can shop this model without flying somewhere, and you will not be the only boat on the market when you sell.

• Recall (USCG/CPSC)

  4 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.

Key West recalls and accident record

These numbers are for the builder, not this model. Check the specific hull with a HIN lookup for recalls and reported accidents.

Recalls affecting Key West

4 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 1720

• Yamaha 4-stroke outboard (F70–F300) 4 listings · 13% of our sample

  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.

Key West 1720 specifications

Rows marked "our listing data" are measured from listings, not published by the builder, and will differ from a brochure. Rows without a source we can name are not shown at all.

What to inspect on a used Key West 1720

1. 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 4 of the 32 1720 listings we track.
2. 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).
3. 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. 96% of the listings we observed for this model are in coastal states.
4. 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 1995, so boats over 31 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 1720 listings. It is not a generic pre-purchase checklist, and it does not replace a surveyor.
