BUILT ON A CHAMPION'S LEGACY
BTH Marine is a family-owned boat dealership and full-service marina in Key Largo, Florida, founded in 2023 by Tommy 'Chief' Hofstetter, a five-time World Champion offshore powerboat racer. We serve boaters throughout the Florida Keys and South Florida with boat sales, Mercury repower and service, and full marina facilities.
BTH Marine was founded by Tommy 'Chief' Hofstetter, a 5x World Offshore Racing Champion whose engines powered iconic championship teams.
BTH Marine, named for Blye and Tommy Hofstetter, was born from a father's desire to share his life's legacy with his son. Every boat we sell and every engine we touch carries the weight of a championship pedigree.
This isn't just a marine business. It's a family legacy on the water.

Our factory-trained technicians handle everything from routine maintenance and engine repowers to electronics installation, Seakeeper gyroscopes, custom welding, boat wraps, upholstery, and full vessel customizations.
Our full marina facility features an 80-ton travel lift, oceanside access, and boat storage - giving us the capability to haul, store, and service vessels of virtually any size.
MORE THAN A DEALERSHIP
At BTH Marine, the relationship doesn't end when you drive off the lot. It's just getting started.
We sit down with you, understand what you want from your time on the water, and help you find the right boat for your lifestyle and your goals. We get on the boat with you, show you the waters, and make sure you're set up for success from day one.
When it's time for upgrades or customizations, we're honest with you. If something doesn't fit your budget, your boat, or the way you use it, we'll tell you. Our job isn't to sell you things. Our job is to set you up for success on the water.
We service your boat, help you upgrade when you're ready, and when the time comes to move up, we'll help you sell it too. We're with you for the whole journey.
You'll find us at the sandbar. You'll see us at Alligator Lighthouse. And if you need us in the Bahamas, we'll find a way to get there.
When you become a BTH Marine client, you become part of the family. And we never leave family hanging on the water.
