Running an outboard motor that has a generator without a battery is bad?
i'm kinda embarrassed to admit this, cause I have a degree in Electrical Engineering, I just wasn't thinking...
I ran my outboard all summer without connecting it to a battery. It's a Yamaha 8hp electric start and alternator, with pull start too, so I've just been pull starting it and had the leads that would normally connect to a battery just covered and isolated. duh.
When I pulled it this fall for maintenance, I started thinking.. you know, it probably is very damaging for that alternator to run without a load of any kind. I'll know if I did any damage when I do the maintenance and then re-install it with a battery but it sucks I didn't think of that earlier.
What is everyone's opinion on this, I was pulling it out when it dawned on me, don't know if it's common knowledge or not.
