I kept putting it off while not using the boat for a couple of months. I few weeks ago, I decided that it was warm enough to take the boat out for a spin. Well, I got the boat backed into the water, turned the key, and it just moaned a little and died on out. Crap! Anyway, I secured it to the trailer, pulled it back home and charged it. Since I learned the hard way not to ignore the batteries while being parked for a while, I went and purchased a pretty nice battery maintainer to keep hooked up all the time while the boat is not in use. I'd also been going out every few days, connecting the water hose to it, and cranking just for piece of mind. This past weekend, after the ice storm, and the weather warmed up to a nice 75* - 78*, I turned the key while it was still in the driveway, just to see if it would crank. It fired right off, and I quickly turned it right off since it proved that it had a nice charge. I took it to the ramp, backed it down and turned the key while it was still on the trailer. Nothing. It didn't bump or anything. I checked to see if the battery cut off switch was in the correct position and found that it was. I couldn't figure it out, so I figured that if it cranked on the drive way, I'd just pull it back out to the level parking lot, and try it again. If fired right up! I backed it on down again, where it was almost flat in the water, tried it again, and it fired up like it was supposed to. What could have caused that? Do these have some kind of safety that prevents them from firing if there's too much angle of the boat, such as angled down into the water on a ramp?
