i have a 2002, 200 hp hpdi yamaha, the oil alarm went off and the engine slowed to 200 rpm's i checked the engne oil resivoir and it was very low. before this hapend the alarm went off and the boat oil resivoir was very low and i added 4 gallond of oil. now the oil is not transferring to the resivoir on the engine. when i through the emegency switch on the oil does transfer from the boat tank to the engine tank. i have checked the wires from the engine oil sencer to the ecm to the boat oil tank all seam to be good i have battery voltage to the oil pump and back out to the yellow wire inside the engine cover. what turnes the oil pump on besides the oil sencer in the oil resivoir on the engine? i have switched the sencer with a none good one the ecu as well. thanks
