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.



BTH Marine is a certified Mercury Platinum Elite Repower & Service Center and one of a select few facilities in the country certified to service the Mercury V12 Verado 600.
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.

BTH Marine carries an exceptional selection of custom-built Front Runner center consoles and catamarans alongside Broadwater Bay Cats, plus a curated inventory of pre-owned fishing boats, offshore vessels, and bay boats.
Based in Key Largo, our team works with buyers from South Florida, the Bahamas, and beyond to match every angler and boater with their perfect vessel.

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.
