The only problem was the water pump seems to be trying to pump
in the wrong direction. It's a gear pump that drives right off the
engine (no belt). I'm guessing that the two gears in there were just
put in backwards. This should be very easy to fix.

It looks like the housing is installed correctly but the gear section,
the center section, is up side down. Looking down, as you are in the
25th photo, the idler gear is on the left. To change the direction of
flow, you need the idler gear on the right keeping everything else the
same. This will move the housing to the right a little. Hope the hoses
will give you enough room.

Beautiful work!!
Beautiful boat!!
Nice job fellas!!
