Marine Services Technicians

Marine services technicians work on the more than 16 million boats and other watercraft owned by people in the United States. They test and repair boat engines, transmissions, and propellers; rigging, masts, and sails; and navigational equipment and steering gear. They repair or replace defective parts and sometimes make new parts to meet special needs. They may also inspect and replace internal cabinets, refrigeration systems, electrical systems and equipment, sanitation facilities, hardware, and trim.

Workers with specialized skills often have more specific titles. For example, motorboat mechanics work on boat engines—those that are inboard, outboard, and inboard/outboard. Routine maintenance tasks include lubricating, cleaning, repairing, and adjusting parts.

Motorboat mechanics often use special testing equipment, such as engine analyzers, compression gauges, ammeters, and voltmeters, as well as other computerized diagnostic equipment. Technicians must know how to disassemble and reassemble components and refer to service manuals for directions and specifications. Motorboat workers often install and repair electronics, sanitation, and air-conditioning systems. They need a set of general and specialized tools, often provided by their employers; many mechanics gradually acquire their own tools, often spending up to thousands of dollars on this investment.

Marine electronics technicians work with vessels' electronic safety and navigational equipment, such as radar, depth sounders, loran (long-range navigation), autopilots, and compass systems. They install, repair, and calibrate equipment for proper functioning. Routine maintenance tasks include checking, cleaning, repairing, and replacing parts. Electronics technicians check for common causes of problems, such as loose connections and defective parts. They often rely on schematics and manufacturers' specification manuals to troubleshoot problems. These workers also must have a set of tools, including hand tools such as pliers, screwdrivers, and soldering irons. Other equipment, often supplied by their employers, includes voltmeters, ohmmeters, signal generators, ammeters, and oscilloscopes.

Technicians who are field repairers go to the vessel to do their work, perhaps at the marina dock. Bench repairers, on the other hand, work on equipment brought into shops.

Some technicians work only on vessel hulls. These are usually made of either wood or fiberglass. Marine fiberglass repairers work on fiberglass hulls, of which most pleasure crafts today are built. They reinforce damaged areas of the hull, grind damaged pieces with a sander, or cut them away with a jigsaw and replace them using resin-impregnated fiberglass cloth. They finish the repaired sections by sanding, painting with a gel-coat substance, and then buffing.
