I want to put a water pressure gauge on my 1996 Mercury 150 EFI. 2 questions, first, will the motor accept one? I have wires under the console of my 1996 181 that are labeled "water pressure" but they are just loose. and second, if I can, then what range should I buy? 0-15 psi or 0 to 30 psi?
Thanks, Robert
Water pressure is mechanical, not electrical.
You'll rig a small tube from the powerhead to your console.
The wires must be for the light on the gauge then. Where approximatley would the tube go to on the motor?
You'll see a threaded plug on each head, you can put a fitting in either one of those, or you can "T" off the hose from the telltale outlet.
Your gauges are also Teleflex. You can get the PN off of one of the others and look it up on the Teleflex site and come up with the PN for the matching water pressure gauge. A lot of them throught the 90 were Red International Domed. It will come with the tubing and fittings you need to hook it up. There is some info on Tlelflex Gauges in my Information and Links that is post pinned near the top of the ChampioN forum page.
