Yes, the pump is under your feet at the helm... This pump is a known problem... I changed out mine for a newer model under warranty...
Assuming that you have checked the breaker and there is power going to the pump wires:
Remove the square drive screws holding the face of the heater under the helm... The heater has long hoses and you can pull it out and bend it over onto the top of the helm foot box out of your way... Because of the blower on the back of the front panel catching on the edges of the hatch, getting it out requires you gently twist and squirm it until free...
The fresh water pump is mounted upside down under your feet (helm)...
Nick the insulation on the pump wires close to the pump and use your VOM to make sure you have power to the pump BEFORE removing it...
Also, ensure that the hoses are attached and not leaking at the couplings - even a small leak on the intake hose and it will not pump... See if you can hear the pump run...
The hoses attach with quick couplings... Pull the yellow fork out (is really tight) and uncouple the fitting... Removing the front (to you) screws is not bad but the rear screws will teach you a couple of new bad words...
Some have fixed the pump by taking it apart and clearing out PVC shavings from the plumbing left during installation...
My pump would not shut off and I chose to complain and get a new pump as opposed to attempting a repair... The new pump has more pressure, more flow, and is quieter...
In the archives there should be a long, whiny, blow by blow I posted as I went through the process to fill in any details I have forgotten... Now, where did I leave the car keys, dangnabbit...
