Negative earth.

We fitted the smallest 12V battery I could find at our local battery suppliers - some thing like 30Ah iirc

I've got a 40 odd A-H one powering my 60Hp......

Once it's spinning it's self sustaining, so you don't need a huge battery to keep it alive. (especially as you can pull start it!) If you have a ton of electrionics on board there may be an argument for a bigger one....
