 Jack,
It is not a difficult project.

• Where is the 110-volt saltwater pump mounted? I understand it needs to be
below the waterline, but I’m also concerned about a 110-volt cable running
through the bilge if I mount it near a new through hull next to the water
intake for the diesel.  I installed the through hull  forward of the strut
and to strarboard of centerline near the engine raw water intake under the
aft cabin boards.As I recall, the pump cord is a waterproof connection and
the cord should be long enough tto reach your panel, but certainly above
the waterline
• Where do you route the hose from the AC unit and pump  to the through
hull? Would I have to route it back through the stern lockers or is there a
way to get directly under the aft bunk? You have to drill two 1" holes in
the locker floor and it is an easy run down to the pump mounted near the
new inlet seacock. and the return runs back  through the stern locker and
under the reefer compressor to the new outlet in the transom
• Is a 15-amp circuit breaker enough for a 10,000 BTU unit? The specs seem
to say yes. I have a spare AC breaker slot on the old-style panel that
combines the AC and DC connections. Yes
• Warren had his electrical box mounted in the place where my solar
controller and battery charger connect to battery cables. Keeping in mind
that I want to keep AC and DC far apart, is there another recommended spot
for it? You have AC and DC only 12" apart at your battery charger and
behind your electrical panel.. insulate your connetions well and secure all
wires with adeqaute cable clips.

Fair Winds,
