Been there. Know a lot of people who've been there.
Engine doesn't work.
Not us. Two fisherman who drifted through the anchorage.
We heard the faint beep-beep from a 75HP, electric start outboard that wasn't starting. They were prepared. Had an anchor. Seemed to know what they were doing.
But, they couldn't get the thing to start. And. It seems like the killed the battery trying to get it to start.
So I towed them to the nearest boat launch. It was the very least I could do to help someone stranded like that.
