A Marine Diesel Engine Mechanic is responsible for inspecting, maintaining, and repairing diesel engines used in boats and ships.

Effective communication with the crew and adherence to safety protocols are also essential, as mechanics may need to collaborate closely with other marine professionals to resolve complex issues while ensuring the vessel's safe operation.

Company Description

Davis Marine Service was established in 2015, as a vessel maintenance company. The company was originally based out of Florida and operated there for a few years. Then moved back to New Jersey in 2018, where we have been operating since. In the beginning it was just Tim Davis performing all aspects of the job up to 2020 when Matt Davis came aboard in May and Mike Davis shortly followed in September 2020. Davis Marine Service continued to expand and now seven employees that specialize in diesel engines and control systems. We are currently in the process of building a new shop not far from our current location which will allow us to take on more projects and further grow the company.
