2018 Formula 280 SS — Should You Buy One?

Typical asking price: $55,000–$82,000. There are 2 high-severity known issues you need to know before handing over a check.

Kestrel Take

Formula builds premium fiberglass performance cruisers with exceptional fit and finish. The 280 SS is a high-quality boat that holds value well and was built to last. Twin MerCruiser stern drives mean double the bellows and impeller maintenance — budget accordingly.

Known Issues for the 2018 Formula 280 SS

Ranked by wallet impact. These are documented, recurring problems — not freak accidents.

Twin MerCruiser stern drive bellows (both units)High — wallet impact

Two stern drives means two sets of bellows, two impellers, two sets of zincs. Bellows on both units must be inspected — one failure is a sinking risk.

Repair cost range: $600-$1,400 for both units preventive

Freshwater cooling system serviceHigh — wallet impact

The closed cooling system requires coolant changes every 2 years. Neglected coolant corrodes the heat exchanger.

Repair cost range: $200-$600 maintenance, $2,000+ if exchanger damaged

Upholstery condition on a boat this ageMedium

Premium vinyl upholstery on a 2018 boat shows age — check for cracking, UV damage, and seam separation.

Repair cost range: $1,500-$5,000 to re-upholster

Walk-Away Red Flags

  • Bellows on either stern drive showing cracks or being milky
  • No coolant system service in the records
  • Upholstery that is cracked or peeling significantly

Good Signs

  • Annual MerCruiser dealer service on both drives
  • Coolant changed on schedule
  • Stored under cover — upholstery in good condition
