When we took our boat out at the launch, it started fine... was idling rough but stayed running. Got out on the lake idling, doing ok. But when we tried to speed up a little, the boat died. It wouldn't crank, starter won't turn. Tried jumping the starter to crank, but it wouldn't do anything. Also tried tapping on the starter, but got nothing. The boat is getting gas. Electrical is completely dead. All the gauge positions stayed right were they were at (at running) and wouldn't reset even when boat was shut off. Any ideas what the problem might be? Thank you!
