Marine Alternator

The Starter Motor Alternator Company, specialist suppliers of quality replacement alternator parts for various aquatic engines. In the water-borne environment the electrical parts are left unused for great periods of time, often in an inhospitable environment. 

However, the main reason for failure on a boat is not due to over use. In fact the alternator experiences relatively low usage. Most of the problems occur due to diode rectifier failure, overloading or overheating. A high output marine alternator is often a good idea to reduce the risk of these types of failure. Also, regular cleaning is important for effective maintenance.
