How is this self priming pump activated? Float switch, timer etc?

The bilge pumps in my boat are mounted on some small "pads" that are

into the bottom of the hull. This pump mounting pad is about an inch
thick.
The forward bilge area always has some water in it because the air
conditioner drips in there and the shaft seals drip a bit. The problem
is
that the way the pumps are mounted, there is always about 3 inches of
water
in the forward bilge area, due to the fact that the pads elevate the
pumps
slightly and the pumps don't pump everything out anyway

I'm looking for an idea to remove all or almost all of the water from
the
bilge. I envision a pump that has a hose on it that will sit in the "V"
of
the hull and pump almost all of the water out. I've just never seen one
and
don't know if anyone has a better idea.


My bilge water collects in a hollow in the top couple of inches of the
molded keel.
There isn't enough width to set one of the common plastic bilge pumps
that sucks up the water it's sitting in. I use a remote mounted 12-volt
self priming pump and a hose that is laid into the keel. Very similar
to the idea you're considering. I think the pump is a lot sturdier than
the plastic disposables, and has proven more durable. I can compare
because I do use a big-box Marine submerged bilge pump to drain the
shower sump.
Every 3 years or so, that shower sump pump needs to be replaced. The
next time I replace it, I'm going to spend the extra dough to get
another remote pump. It has occured to me that if I ever needed to move
a lot more water out of the bilge I could just move the pickup hose
from the shower sump into the bilge.
