Normally you need to turn the water pump switch "On". The pump will kick in when you turn the faucet on. Is the water pump getting 12 volts?

It should operate the same fashion as rv water pump...Supply 12v to the hot side of pump and with water in your system it should begin pumping. More likely than not the pump seals gave out and are leaking..thats why the switch is missing?? just a guess. Also remember to treat the tank and lines with some bleach to disinfect.

12V supply goes to fuse or breaker panel. it leaves the panel and goes to the dash switch. It leaves the dash switch as a Grn/Brn wire to pump.

Fuse/breaker good ?

Do you hear the pump come on? You also need to check to make sure you are getting 12v to the pump. If you are then the pump is bad.

You will have to trace circuit and all the tips above were excellent. All electrical components need to be checked for proper operation---switch, fuse/circuit breaker, and finally pump. If the pump growls and you still have no water, there could be bad impellor. Make sure your water level in tank is high enough to self prime. If you are not sure where the pump is, find the water tank, and trace the tubing to the pump, or trace from fixture. The tank should have three outlets which have hoses or tubing attached to them---fill (usually a larger plastic hose near the top of the tank which leads to the water fitting on the outside of the hull; Vent--- which is usually a smaller hose, also at the top of the tank. This hose should be connected to vent fitting on outside of hull; outlet--- at bottom of tank with 1/2" tubing or hose attached. Be sure the vent is clear, by blowing through it. Goodluck.

Rich.I Forgot the obvious , ....."is there water in the tank ? " Hope he checked that first.

As far as the wiring diagrams, It's a doit yourself project but that's not all bad. At least you'll know your boat.
