why does the blower have to be up high? blowers are in fact are usually
down
low, and usually have been since the CG started requiring them in 1940
(1942?).

Unless the blower is sumbergable (none that I have ever seen are) you would
want to take care to mount the blower higher than any expected accumulation
of bilge water. Even unexpected amounts!

Many of the cheap blowers are "flange mount" and by design need to mount to
the underside of the deck where the exhaust fitting is located. The hose
connected to the intake of the blower should have its lower end mounted so
that it is as low in the boat as possible but above the normal accumulation
of bilge water, per Coast Guard regulations.
