How to Install a Water Pressure Gauge on a Boat
A water pressure gauge can mean the difference between driving to shore with a healthy engine system or paddling to shore with a damaged one. A water pressure gauge device measures the water pressure that is being dispersed by your boat's engine. While many boats are equipped with pre-cut holes for the installation of a water pressure gauge, not all boats have or used them, but they can make a vast difference on your engine's cooling system.

Relieve the residual pressure in the pressure hose. To do this, loosen the fitting on the end of the engine pressure hose.
-
2

3
Unscrew the water pressure gauge from the front control console and dispose of it in the garbage.

4
Remove the drain pan and empty out the contents.

5
Install a new water pressure gauge. Line up the holes in the pressure gauge with the holes in the front control console. If you don't have any holes in the console, drill a small hole in the front port corner of the lower engine cowling. Measure the diameter of the holes in the water gauge and use a drill bit that will produce holes that are of the same size. You will probably need about a 2 1/16-inch diameter hole for the gauge.

6
Insert and thread the mounting brackets over the gauge mounting studs. Depending on the type of water pressure gauge you have, there could be as many as nine mounting brackets.

7
Insert and twist two external lock washers, the hex nuts on the gauge studs. Tighten them as much as possible. Use a wrench to help tighten all the way.
-
8
Thread the pressure hose onto the gauge on the back of the water pressure gauge. Turn the coupling clockwise to tighten it.

9
Rip off the tag on the electrical wire socket. Use a spill kit to clean up and remove any spilled fluid.

10
Run the lead from the water pressure gauge and connect it to the terminal battery. Connect it to the positive or negative as per the instructions of your manufacturer's guide. Different manufacturers may have different requirements but it should be stipulated either on the wire itself or in the manual.
