Merc 50 pressure gauge

[andrewkafp]

I have a gauge in my boat that says "Pressure"<br />It never seems to register anything and I assume it aint working.<br /><br />There is also a small diam tube the comes out of the head which has what looks like a car tube valve along it.<br />Can be seen between the plugs here ::<br /> http://www.myfishingpictures.com/watermark.php?file=527/1413head-med.jpg <br />Only had the unit for a while, curious as to whether pressure and temp gauges are essential.

There is supposed to be a very small wirelike plastic line that connects to the guage from the fitting you describe.<br /><br />It should read maybe a few to as many as 15 psi at high engine speeds. It's used to indicate waterpump condition and is not an item used in standard trim.<br /><br />Weather or not you want to use it is up to you.

A bit of feedback..<br />Used boat on the weekend, and found that the gauge DOES work. Sits on about 3-5 p.s.i
