I have a 9.8 Hp Nissan (Tohatsu), 4-stroke, electric start on my sailboat. We recently took it off to have it serviced. A guy who was helping me remove the connections from the battery, while I was disconnecting the battery. I now have the motor back on the boat, but I am not sure where to connect the battery leads. The positive connection is pretty obvious (there is a red cover there). But, I am uncertain where the proper ground (negative) connection should go.
