our company

D. Eugene Mastry, a first-generation Lebanese businessman, founded Mastry Engine Center in 1962. Based in St. Petersburg, Florida, Gene raised his family and business to his own personal high standards. Those high standards continued by three of his sons (Constantine, Richard and Adib Mastry) for a combined total of 50 years, a tradition of excellence through maximum customer satisfaction. A recent acquisition by its major supplier, Yanmar, with 100 years of engine manufacturing experience,


gives the company 150 years of combined experience in the diesel engine business. Mastry Engine Center LLC will continue its reputation as the team to turn to when faced with challenging marine diesel powertrain applications and installations, providing solutions both in the O.E.M. as well as the repower market. We currently support a network of over 140 authorized dealers throughout the southeastern United States and the Caribbean.
