Hey guys I am brand new on here and I have a 40 HP 1985ish outboard. The battery in my boat is dead. Is it okay to hook jumper cables up directly to the positive and negative terminal wires just for the compression test? I don't want to buy a battery yet until I know how the compression is. Got the boat and motor for free so I guess I could put a little cash into the project. Im open to any advice!
