WHY BUY PRE-OWNED MOTORS FROM BTH MARINE

Every pre-owned outboard motor at BTH Marine is inspected by our factory-trained Mercury technicians before it goes up for sale. As a Mercury Platinum Elite and Mercury V12 Verado certified facility, we know Mercury engines better than anyone in the Florida Keys.

When you buy a pre-owned motor from BTH Marine you're not buying blind. You're buying a motor that has been evaluated by the most qualified Mercury team in South Florida, sold by a dealer who stands behind what they sell, and backed by a service facility that can support you long after the sale.

We also handle complete repower installations. If you're buying motors for a repower project, BTH Marine can manage the full installation from start to finish.
