As a marine technician, your job is to repair and adjust electrical and plumbing systems on boats, yachts, and other aquatic vessels. To accomplish this, you work with mechanical systems, fix damaged parts, perform regular maintenance to keep things in good working order, and run diagnostics to troubleshoot problems. You may also be asked to install new systems, upgrade existing systems, conduct operational tests, and suggest modifications. You are expected to document all inspection and repair jobs, test the results of work performed, and order parts as needed. Many marine technicians work directly with customers, so customer service skills are essential.
