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.
