Helmut began working with Volvo Penta engines at his parent’s marina in Germany by the time he was 13 years old. His love for boating grew with every day and Volvo Penta engines became his passion! Once he graduated, he went through Germany’s intense trade program and became a master technician for Mercedes. From there, he immediately switched back into the marine industry and was trained extensively at Volvo Penta Europe in Kiel as well as Sweden before taking over his parent’s marina ‘Motorboote Ahollinger’. Born in Philadelphia and raised in Europe, Helmut returned to the United States in 1987 where he and his wife Lisa started Helmut’s Marine Service, a small Volvo Penta dealership in San Rafael.

Helmut's Marine History Volvo Penta Service


With the help of an excellent crew, we became the Volvo Penta Authorized Power for gasoline and diesel engines in CA, HI, AZ, NM, NV, UT, and Guam. In 2013 Helmut’s daughter Nadine and son-in-law Nate joined the family business. Nadine began in the service department as the service writer and now manages the service department along with running day to day operations as general manager. Nate began in the parts department but with his degree and background in engineering, he transitioned into engine sales and applications. Although a lot has changed over the years, two things have remained the same:

  1. We still specialize and exclusively work on Volvo Penta
  2. We are still family owned and operated


Offering the largest inventory of parts and engines with the highest standard of service and support. Helmut’s Marine Service Inc. strives to be a customer-focused distributor of Volvo Penta marine engines.


A Volvo Penta Rapid Response dealer must meet stringent standards. State-of-the-art facilities, diesel parts and tools, and top-notch training — coupled with mobile and fixed-service locations — are all part of a Rapid Response dealer’s commitment to your satisfaction. The Rapid Response service applies to boat owners with diesel engines still under Volvo Penta Warranty. Under this program we will send a technician to your boat within 24 hrs of your call. Our Rapid Response line is 800-326-5135 Ext. 7

Action Service is available to all Volvo Penta customers. In the event you need technical parts or service, Volvo Penta will locate the closest dealer to you and notify them of your problem. This service is free from Volvo Penta if your boat is covered under warranty. If your engines are out of warranty, there is a $50 fee paid to Volvo Penta. We suggest you call us directly if you are in our service area!

In the event a part must be ordered for a Rapid Response call, Volvo Penta guarantees delivery within 72 hours from the Duluth, Georgia distribution center — or the part is free. *Some restrictions apply
