Battery help... See picture

[bguy]

I'm looking to see if any one knows if it would be ok to start my boat motor 1992 Honda 45hp 4stroke.
I was told it came out of a vehicle that hydrogene. It's charging right now. We shall see.

If' the battery is the correct voltage and has enough cranking amps, your motor won't care if it came out of a flashlight, or an electric razor as far as starting goes. I'm not sure about charging requirements. What type battery is it (lead acid, gel cell, etc)? Whether it will stand up to the vibrations and pounding from being in a boat might be an issue though, as some batteries are sensitive to some things.
