Yamaha 4.3 yems flow sensor

[Douggie]

92 Yamaha 4.3 yems V-6 has 2 temperature sensors - 1 for flow in thermostat housing and 1 for temp on engine. Buzzer going off for flow sensor and there is flow. I can't locate a new flow sensor - Checked with local dealer (picture of thermostat housing in their computor doesn't show it or list it) Need one

Re: Yamaha 4.3 yems flow sensor

The water pressure sensor is located in the power steering oil cooler. The cooler is located on the starboard front of the engine way down at the bottom. So actually you have three sensors. One is for the temp gauge, high temp alarm and water flow alarm. Uh, you have checked to be sure the flow is enough to trigger the flow sensor. Just because you have water coming out the exhaust doesn't mean you have enough water. Yamaha has none in stock and cannot be ordered from Japan. I've probably got some in the used parts bin upstairs if you need one.
