About Us

Longhorn Marine Services was built on the belief that reliable engines don’t happen by accident. They are the result of discipline, experience, and doing the job right the first time.

With over a decade of hands-on marine diesel experience, our foundation was developed in one of the most demanding yachting environments in the world — where precision, accountability, and first-time accuracy are non-negotiable. That experience now serves commercial operators, yacht owners, and marine contractors throughout Southeast Texas and the Gulf Coast.

We specialize in preventive maintenance, accurate diagnostics, engine and generator service, cooling system integrity, auxiliary pump support, and reliability-focused marine repair. Our approach is structured and preventative — not reactive — because unplanned downtime is costly and often avoidable.

Longhorn supports vessels operating within the Sabine–Neches Waterway and surrounding Gulf Coast ports, where operational continuity matters. Whether servicing commercial workboats, fishing vessels, or private yachts, our standard remains the same:

Do it right, or do it twice.

Longhorn supports marine operations within the Sabine-Neches Waterway and Gulf Coast ports, where reliability is essential to commercial logistics and operational readiness. Our local presence enables responsive service and preventive care for operators.
