Does my Yamaha outboard charge the battery?
Do Outboards Have Alternators & Do They Charge Batteries? Yes.

At what capacities and loads they charge the batteries is another thing.
How do I know if my outboard motor is charging my battery?
Another simple test is to turn on your boat lights and see if they get brighter after you start the motor (a voltage increase). If the motor cranks after a day on the water but then not the next time out it’s likely a bad battery. If you have the patience you culd disconnect one side of the battery after coming in.
Can an outboard motor run without a battery?
an engine will run without a battery no different than jumping a dead battery with a good one, once the engine starts you remove the jumper cables and it continues to run.
Can a dead boat battery be recharged?
Recharging them is extremely important because they lose electrolytes during normal use, but it’s worth noting the following about charging: overcharging or undercharging a battery can do serious harm. undercharging causes damaging lead sulfate to build up.
How long will a boat battery stay charged?

Can you overcharge a marine battery?
2) Overcharge and undercharge Essential to marine battery maintenance is proper charging so always use a charger that meets the manufacturer’s recommendations. Excessive or incorrect overcharging can be equally damaging, particularly with AGM and gel batteries.
Will a boat run with a bad alternator?
Boat Battery Often Dies (Discharges Deeply) The alternator provides the necessary electrical power whenever your boat’s engine is running. Obviously, batteries sometimes fail on their own–but a bad alternator can actually cause the battery to drain because it’s failing to recharge the battery.

Unless you live several hours away from where you store the boat, and you leave the boat for a few weeks at a time.
Can you recharge a dead marine battery?
Deep cycle batteries are unique power sources for marine applications. They’re designed to be discharged down to practically no power at all, and then you can charge them back up to a brand-new state.
Will an outboard motor charge two batteries?
Just connect a COMBINER 100 between the starting battery and the trolling battery. Whenever the outboard engine is running, the combiner will share the charging output with the trolling battery. No voltage drop so both batteries get the full charge.
Does revving engine charge battery faster?
Revving your engine does charge your battery faster, but only when the battery is in a significant state of discharge. Revving the engine will charge the battery faster because the alternator increases this amperage. When you rev the engine, the alternator begins to run faster, which helps charge the battery.
