The fresh water pump is under your feet when you are sitting at the helm. Take out the heater grill and core and you should have enough hose on the heater to lay it to the side or tie it to the helm to keep it out of the way. Do not disconnect the heater hoses. The potable water hoses will probably have quick-connects on them and are easy to take off. The potable pump should be screwed to the floor above it. The back two screws have to be taken out by braille. If there is not a strainer in the intake hose coming from the potable tank, I would recommend cutting one into the intake hose where you will be able to reach it with the heater out of the way.
On mine the transducer is starboard side, maybe 14 to 16 inches forward of the transom, not too far from the stringer, and glued to the inside of the hull. Looks like 1/2 of a soup can with wires going to it. You should be able to see the wires coming into the top of it. Having said that, others have said the location may vary a little. Theoretically it is accessible from the hatch under the tank/locker under the aft hatch in the center of the stern.
