Installation – Done Safely, Done Correctly

We got our start as a small marine engine service company, a place where removing old engines and installing new ones is a daily task. Because of our roots and our continued connection to the marine market, our technicians are very experienced in the installation and alignment of diesel engines and generators. As certified installers for many of the industry’s major brands, we know the value of getting an install right the first time. Before we leave the job site, we take the time to ensure everything is done correctly and works like it should.

Building On Decades of Trust

With over thirty years of experience under our belt, we’ve earned a reputation for the reliability of our service. Our team of OEM-certified experts has developed unparalleled know-how over the years and can get your equipment back online with all repairs carried out in compliance with OEM specifications and procedures.

Industries We Serve

Our heritage lies in marine transportation, but our expertise extends to a variety of critical industries including hospitals, government & emergency services, chemical plants, refineries, and just about every other heavy industry sector. No matter the industry or the project, we provide our customers with the same high-quality service, fast response time, and dedicated experienced technicians that have made us the partner of choice for so many of our customers.
