The M550-A404 Stator Generator Alternator is a high-performance component designed specifically for Yamaha F75, F80, F90, and F100 4-stroke outboard engines manufactured between 1999 and 2004. This alternator is an essential part of your outboard engine's electrical system, responsible for charging the battery and powering the various electrical components of your boat.
The M550-A404 Alternator is a 3-phase, 12-volt unit with a nominal output of 40 amps. It features a robust and durable design, with a cast aluminum housing and a high-quality, double-shielded stator winding. This design ensures reliable operation even in the most demanding marine environments, resisting corrosion and withstanding the effects of saltwater and UV radiation.
The alternator is equipped with a heavy-duty, 8-rib, 16-Volt diode rectifier design, which efficiently converts the alternating current (AC) generated by the rotor into direct current (DC) for charging the battery. This design ensures optimal battery charging performance and extends the life of your battery, ensuring your boat is always ready for action.
The M550-A404 Alternator is also equipped with a high-quality, self-regulating, automatic voltage regulator (AVR). This regulator ensures that the charging voltage delivered to the battery is always within the optimal range for optimal charging efficiency. This helps to prevent overcharging, which can damage the battery, and undercharging, which can leave the battery insufficiently charged for starting the engine.
The alternator is easy to install, with a simple bolt-on design that requires no special tools or modifications to your outboard engine's electrical system. It is compatible with standard Yamaha wiring harnesses, making installation straightforward and hassle-free.
In summary, the M550-A404 Stator Generator Alternator is a high-performance, durable, and reliable component that is essential for the proper operation of your Yamaha F75, F80, F90, or F100 4-stroke outboard engine. Its robust design, high-quality components, and easy installation make it an ideal choice for boat owners who demand the best from their marine electrical systems.
