We are GM Marine Engine Technology
The marine environment is uniquely demanding. We understand this better than most…
For more than 40 years, we have supplied some of the most respected names in the marine industry with world-class powertrains for their stern-drive and inboard watercrafts. Leveraging more than a century of GM engineering and design, we pride ourselves on the production of marine-ready powertrains that are second to none. To help ensure that our engines meet the strenuous demands placed on them in the marine environment, we have an extensive development process that few manufacturers can match.

Utilizing our state-of-the-art Powertrain Testing Facility and Marine Development Center, our engines go through a validation process that includes thousands of hours of real-world testing in some of the harshest environments imaginable. This "tested-tough" process, coupled with our use of the latest engine technology and design—which includes advancements such as Variable Valve Timing and Active Fuel Management—results in an exceptional product.

From there, our capable engines are refined by a select group of marine-engine manufacturers for use in an array of watercraft. These “marinizers” engineer and upfit our powertrains with additional marine-specific advancements necessary for their boatbuilding partners to integrate the engines into their product lines.

When making the big decision to purchase a boat, insist on the proven performance of GM Marine Engine Technology to confidently power your passion for years to come. Check out our portfolio of products and discover why our partners trust our engines to stand up to the rigors of the marine environment and deliver exceptional performance and dependability again and again.
