Would one of those portable battery/chargers start my boat? its rated 400 -900 cca. Ive got a 2006 150 optimax. Ive been thinking about keeping one on board in case my boat wont start when Im out on the water. But Im not sure if the portable would crank the Opti. If someone has tried it I sure would appreciate some feedback. Im going to a fairly remote spot very soon, and thought it might be a good idea to have the backup on board rather than jumper cables as there might not be anybody else around when I need the help.ThanksBob
