Mercury 225 EFI 4 stroke will not crank over even with brand new battery. The engine cranks for split second but not enough to start motor. Thought it was the battery having low charge so replaced with new battery. Still would not crank the engine enough to start. Acts like dead battery still. All wires were cleaned at battery. Connected the engine wires only on new battery and still acts as if the battery is weak. Get half crank and then nothing.
What else can it be.
