Re: Water Pressure Gauge
rprichoux <br /><br /><br />Outboards are cooled by water, that water comes from the lake, river, ocean etc, that you are running in. <br /><br />The outboard has a pump, with a rubber impeller. The water pressure gauge, tells you that the pump is picking up water, and pumping it thru the block. The other way to tell is the pee hole, it should have a steady stream of water coming out of the side of the motor.<br /><br />I am not sure what type of gauge you have, but if you look at the back of the intrument panel, you can tell. It is either mechanical, or electrical. <br /><br />If it is mechanical, there will be a tube that runs from the gauge back to the motor. On the motor, it will connect into the block. When the pump is running and you have water, the pressure, pushes on the gauge, giving you water presuure. <br />If it is mechanical and it is not working, the problem could be, clogged line, clogged fitting, bad gauge, or no water pressure. Even if it is mechanical, there may be wiring going to the gauge for lighting. Do get confused.<br /><br />If it is electrical, there will be wires running from the gauge to either the wiring harness or the motor, to a pressure sensor on the block. Then the problem would most likly be a bad sensor or bad gauge.<br /><br />The fact that you have a switch label water pressure seems odd, because you would not need a switch on a gauge. Are you sure it is a switch not a circuit breaker? Or could it be for a water pump, like a wash down pump?<br /><br />Trace the wire from the switch and see where it goes.<br /><br />If, you get no response on the gauge, and no water on the pee hole, I would check into it further ASAP. How old is the impeller??? They should be replace once a year, maybe every other year at the most. <br /><br />You can also run a small wire into the pee hole, to see if it is clogged, Mud wasp love to make homes in the hole!!!!<br /><br /><br />Good luck.
