Does an outboard engine recharge the battery when running like a car does?

[jash1178]

Was wondering this or do I need to monitor and recharge my battery as necessary?

Almost all electric start outboards have an alternator to recharge the battery. If the motor has not been run for a while, it always a good idea to put it on a charger before you take it out. Particularly on smaller motors whose alternators charge slowly. This makes sure you will have plenty of battery to crank for awhile if you have to. Most of us hook up water to the motor, crank it and let it run for a while before we leave home.

most electric start motors will charge the battery, to maintain it for starting. if you plan on electronics, radio etc, you need another Deep Cycle battery for them. motor only put out a very small charge at slow speeds, most charging is done at fast speeds.

I hate getting caught with a dead battery so I charge mine before every trip just because, but yes, the do charge if it is working correctly.

Easy to check, measure voltage with the motor off then again with it started and running, should be more when running, DO NOT disconnect the battery when the motor is running it will fry the rectifier or regulator, can't remember which but they are both expensive and the faster the engine is turning the more charge it puts out but don't run the engine above 1500 rpm without a load on it.

Some do and some do not as stated above. Most electric start motors do charge, however there is nothing more reassuring than having a spare battery out with you. I always take one of those power packs that can boost start the motor if necessary.

What sort of motor do you have? Year, hp, make.

Install a volt meter, then you will always know if your charging circuit is working properly.

And if it's not ??? when you are out there ???
