Responsible for propelling a ship across the sea, marine engines are heavy-duty engines that make use of as much low-torque as possible for prolonged periods of time while withstanding corrosion and tribulations of the sea that would put a regular engine out of commission. Whether you are looking for a diesel engine, a natural gas engine or a marine engine that can handle anything the sea will throw at it, Surplus Record is here to help weather storms at sea and on land.
