Volvo Penta Commercial & Defense Vessel Repowers

Power. Precision. Proven Performance on the Water.

At Helmut’s Marine Service, we specialize in Volvo Penta repowers for commercial and defense vessels — delivering reliability, fuel efficiency, and uptime where it matters most. Whether you operate patrol craft, workboats, or high-speed commercial vessels, our factory-trained team ensures your operation runs at peak performance.

With TWIC-certified technicians, direct access to Volvo Penta Power Center support, and over 37 years of experience, Helmut’s is trusted by fleet operators, shipyards, and government agencies across the West Coast and Pacific territories.

We are committed for the long haul — well beyond the installation. We know commercial operators rely on uptime, and when a vessel is down, every hour counts. That’s why both our Service Department and authorized dealer network prioritize commercial support with fast parts availability, rapid diagnostics, and expert repairs to get you back on the water quickly.

And don’t just take our word for it — we’ll gladly connect you with commercial operators who can speak firsthand to our rapid response, preventative care approach, and unwavering dedication to minimizing downtime.

Whether you choose installation through our Service Department or prefer to work with your local yard, we’ll provide the operational support you need throughout our Area of Responsibility — today and for the life of your equipment.
