Ok so my brother 76 hondo with a 455 olds in it keeps stalling out. Its a Whole other issue. Anyways As we were trying to start the boat agian. We kept hearing this clicking sound. But the starter wouldnt turn over.Brand new batteries. Anyways so we keep inspecting and the clicking sound isnt coming from the starter its coming from the black thing with 4 screws and 2 white wires and one red wire on it. its located up by the valve cover on the rear of the motor. Anybody know what that is and why its clicking and the starter isnt turning over?
