There are many different types of boats from speedboats to fishing vessels, jet skis, and cabin cruisers. In order to keep them in good working order they need to be regularly maintained and serviced. Most marine technicians enjoy using boats for pleasure or fishing in their own time. It makes sense to find employment doing something you enjoy. Problems often need a certain amount of detective work, so if you like problem solving, discussing symptoms with people and using your hands, then this could be the career for you.
According to the Bureau of Labor (U.S. Department of Labor, Occupational Outlook Handbook, 2006-07 Edition, Small Engine Mechanics) opportunities for employment are to grow at about an average rate. The good news however is that prospects for properly trained and qualified marine technicians are particularly favorable. The 40-50 age group is growing, and it is these people who are most likely to want and own a boat.
Conditions and pay vary depending on how large your employer is. Small independent shops maybe will pay less than large national organizations. The benefits in these larger marinas and repair shops are usually better too. Your employer is more likely to pay for further training. This training often takes the form of learning how to work on a particular brand, for example when a new model or design is launched. This benefits everybody, since your training will be up to date, and the service you and your company provide will be improved. Customers will enjoy a better level of care, and so will return for repeat business. The armed forces, police, and coastguard services may also appeal to you.
