Really considering getting a Phoenix 920 coming out of a Ranger Z20. I can't seem to find any pics of the area where the livewell pumps and bilge pumps are located. How difficult are these to replace should one go out on the water? In my Z20, I can look down at a certain angel and see all the pumps and even my shoot through hull transducer. On the phoenix boats, all I see in the back compartment is the batteries and no other visible way to get to the pumps.
