Key West 1720 Sportsman

Typical used values

Ranges interpolate 3 hand-anchored years at 5%/yr depreciation off-curve. Hours and saltwater service further adjust; a full Deal Report scores those for a specific listing.

Known issues to check (2)

• Low Few systemic hull problems; the risk profile is age-standard — fuel tank condition on 2000s hulls and console wiring on heavily accessorized boats.
• Medium Popular first saltwater boat, so flushing and anode discipline vary wildly; the engine's salt exposure history is the real variable.

Pre-purchase inspection checklist

1. Fuel tank inspection port check on pre-2012 hulls.
2. Outboard midsection and bracket corrosion assessment.
3. Verify trailer condition and title accompanies the package.

Typical engines (2)

• Yamaha 4-stroke outboard (F70–F300) outboard · gas · base score 90/100 · high-use ≥ 150 hrs/yr

  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.

  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.

• Suzuki 4-stroke outboard outboard · gas · base score 86/100 · high-use ≥ 150 hrs/yr

  Underrated, highly reliable 4-strokes — Suzuki effectively pioneered the modern big 4-stroke outboard. Slightly thinner dealer network than Yamaha/Mercury in some regions, which is the only real resale knock.

  100-hour service; check the timing-chain-driven valvetrain history on high-hour units. Confirm a Suzuki dealer is reachable in the buyer's area.

Resale liquidity (81/100)

The strongest-resale boat in the entry inshore CC class — Key West's build reputation pulls demand a clear step above same-priced competitors.
