Marine engine mechanics are responsible for repairing the engines of boats and ships. They may be self-employed, or they may work for a company in the boating industry. Common tasks performed by marine engine mechanics include examining engines and equipment to locate problems, taking apart engines, and repairing or replacing parts that are defective; they then reassemble the equipment. Marine engine mechanics use hand tools, power tools and other equipment such as chain hoists to remove engines and replace them.
After the engine has been repaired and reassembled, it is connected to all lines, controls, the shaft and the propeller; then, the marine engine mechanic tests the engine using specialized tools such as a tachometer and voltmeter to ensure that it is running correctly. They let the engine run so they can check revolutions per minute, pressure and temperature, making adjustments as necessary. These mechanics may also make some smaller replacement parts themselves using specialized machinery. Additionally, marine engine mechanics may record all gauge readings in an engineering log, test and repair other parts of boats and ships, order any necessary parts and bill customers (if self-employed).
Marine engine mechanics generally must have an associate's degree in marine mechanics, or they may also enroll in a shorter program for a certificate. Previous experience is generally required or preferred as well. It is important that they enroll in continuing education so they can stay up-to-date on engine technology as well.
