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.
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
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
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
