2017 Boston Whaler 170 Montauk — Should You Buy One?

Typical asking price: $22,000–$36,000. There is 1 high-severity known issue you need to know before handing over a check.

Kestrel Take

The Montauk is legendary for a reason — its foam-filled hull literally cannot sink. Whalers hold their value exceptionally well and are built to last decades. The main concern on a used one is deferred outboard service and the premium you pay for the name.

What we checked

No public record to reconcile against

We don't yet have a public record to check this one against. Boats and personal watercraft are not in NHTSA’s database — that is the Coast Guard, which publishes recalls but no owner-complaint record. What follows is our own write-up, and it has not been reconciled against an official record. Treat it as a starting point, not a verdict.

Known Issues for the 2017 Boston Whaler 170 Montauk

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

Outboard service history gapsHigh — wallet impact

Whalers last forever; the outboards don't if neglected. Lower unit oil, impeller, spark plugs, and zincs need annual attention. Verify service records on the motor specifically.

Repair cost (estimate): $200-$3,000 depending on what was neglected

Source: not yet checked against public records.

Livewell pump failureMedium

Livewell and washdown pumps fail from prolonged non-use or salt exposure. Easy fix but check function during sea trial.

Repair cost (estimate): $100-$300

Source: not yet checked against public records.

Console wiring corrosion (salt water use)Medium

If used in salt water, the console wiring can corrode at connections, causing electrical gremlins — gauges, lights, bilge pump.

Repair cost (estimate): $200-$800

Source: not yet checked against public records.

Walk-Away Red Flags

  • Outboard with no service records
  • Salt water use without documented freshwater flushing after each trip
  • Any electrical system not functioning during inspection

Good Signs

  • Mercury or Yamaha outboard with annual dealer service
  • Freshwater use history
  • All electronics and pumps functioning on inspection
