Does An Outboard Motor Charge The Battery. Almost all outboard motors have what is called a rectifier that acts the same way as your cars alternator does and this charges the battery as the engine is running. Generator coils that create electrical current unregulated AC from the motor.
If you plan on electronics radio etc you need another Deep Cycle battery for them. NEVER jump-start a battery while an outboard engine is running. The outboard uses a stator just like an alternator that will charge the battery while it is running.
Most electric start motors will charge the battery to maintain it for starting.
Its not designed to charge a dead or weak battery. How You Should Connect If you want to connect the trolling battery to the outboard motor you need to use a combiner that will connect between the trolling battery and the starting battery. While running the boat the day before today I determined to isolate the motor battery from the electronics battery just in case I I assume when I eventually determine out what is going on with the charging difficulty I will in the end do what you. Youll get better charging at 1000 to 1200 rpm than idle.
