Diesel Marine Specialists
Tony, Corey and the entire Seaboard Marine team are absolutely awesome. I have been actively involved in all aspects of the marine industry for 35 years and it is rare to engage in such a great company such as SBMAR. They are always eager to help you and their knowledge pertaining to diesel engines is invaluable. If I could I would give them 20 stars !!! You guys are the best.

Seaboard Marine is Top Notch
I find myself incredibly 'lucky' that Seaboard Marine exists. That being said, Seaboard Marine is the best choice for Cummins.
