Many boats have multiple batteries, and much heavier duty than a car. A cheap jump pack may not have the "oomph" that a "professional" grade has. I had dead batteries and a fully charged box. No go. Borrowed the heavy duty one from the Marina and started right up. Now I have a top of the line that also can run AC. Being well prepared, now I never need it, but it also blows toys up faster. and I don't need a separate air pump. There is a separate thread about jump packs and alternatives.
