Now that I have the hot water line in, it's time for the cold. Now I put the "tee" where I SHOULD have put the one for the fake-a-lake, now that I see there is room. This hose was a bugger to get out, not much room to work down there.

Getting the "tee" into this hose was also a "joy" -- even with soapy water inside the hose, and heating the hose up, it took a LOT of pressure and me and my 21 year old son about 10 minutes:



Back in place in the boat, with the cold water line attached:



Hot and cold lines to the mixing valve (not back in the boat yet) -- then
you have to cut the supply line that goes from the mixing valve to the pump,
and then to the actual "shower" head.



Box back in place, shower head attached (all the hoses are also now hooked
to the mixing valves)
