Dometic 711 Head Install

Hi Friends,
Still refitting the Irwin 44
Older boat, two heads but no holding tanks.
The plan is to leave one a direct overboard
head with the proper lock outs.
The other one we are not really up for the task
of cutting things apart to install a proper
large holding tank so we plan on installing
a Dometic 711 self contained MSD.
Thanks to Peggy for mentioning this unit in
her book.
The question is,in addition to a deck
pump out, we want to be able to empty at sea
so iíve come up
with the configuration in the attached drawing.
Iíve scoured the forum and other sites looking
for an exact diagram of what I want to do
and havenít found anything.
So will this work and be odor free?
I am well aware of the pertinent discharge
and lockout requirements so no need to beat up
on that aspect.
Vented loop of the overboard discharge to be
above heeled waterlines.
Any comments on a macerator as opposed
to a whale gusher diaphragm type pump?
Thanx all
Definitely out of my wheelhouse here
