Guessing by the size of the motor you got, it probably already came with clips on it. Be sure the motor is in the "OFF" position, clip the RED cable to the + (positive) side of the battery and the BLACK one to the - (negative) side. Or it may have came with round eye terminals, which need to go on the post & wingnut usually found on marine batteries.
You need a battery box, they're cheap, to set your battery in. If you plan to leave the battery in the boat while on the road, you need to find a way to strap it down. Might be simpler for you to carry the battery in the vehicle & put it in the boat once you get to the ramp. Still, set it in a way it won't tip-over in the vehicle.
