Have twin Y. 250<br />Port engine will not pump oil up from remote oil tank to engine oil tank. Oil pump on remote tank is new. When manual switch is activated pump on remote tank runs and oil is pumped up (confirmed).<br />When boat is run, engine alarm goes off when engine oil tank runs low. Fill manually and alarm stops and motor starts/runs. Have checked sensor floats with ohm meter as per Yamaha manual (4.5 to zero ohms - all four check points; checked floats from both engines and got same readings; starboard engine works as it should)<br />If you turn off the key in the ignition and then turn it back on the pump will start pumping oil up if the oil is low in the engine tank. If you take off the drain 'tube' on the bottom of the engine oil tank and drain the oil out (with the switch on) the pump will not start to fill the tank as the oil runs out (the thought was to simulate using up the oil as your run the boat). Two arrows on cap and side of the engine oil tank are lined up. Float is free from dirt, or sludge. For some reason when the float drops a 'message' is not sent to the pump motor to start running. But if you turn off the switch and turn it back on it works. This sounds like there is some kind of 'logic'device between the engine oil tank float and the oil pump on the remote tank that is not working.<br />The pump works. The float checks out.<br />Have switched floats to no avail.<br />Has anyone run across this one?<br />Tom Wadsworth
