It is extremely simple to do. The hardest part is running the line from your bow back to the rear of the boat. Most places use PVC and glue it together then glass it to the hull. The pickup is in the back and you have to transport the water to the front. Any way you want to do this will work. I have seen some people use garden hoses and they do work. Not the cleanest, but they work.
1) You will need to install a water pickup on the boat (typically on the inside of the tunnel right at the back).
2) You then will mount the pump in the engine compartment.
3) Run the hose from the engine compartment to the front of the boat
4) Run two wires from the location of the push button on the front to the back.
5) Hook up the intake to one side of the pump and the other to the hose for the front.
6) Install the shower on the front and hook up the hose.
7) Install the push button on the front and hook up the wires.
DCB has the trick 5 hole showers that deliver a nice clean stream, but for ease of use and parts that are ready available, Dana Marine makes a fuel vent that works perfect. Two holes approximately 1/8" high by 1/4" long.

This is the type of pump that you will want to use.

You can either use a momentary switch similar to this one

Or you can use a push button like DCB did.

It may sound complicated, but they are actually very easy to install. The hardest part about the whole thing is running the wires and the pipe from the front to the back. Easy when it is being built but with interior it can be a pain.
Hello, we were build a kit and sell them......... You just blew it!
