Re: [Paddlewise] Electric Pumps ??

Cole Hersey makes a switch that was marketed to the PWC users.  It is a
single pole single throw switch.  The switch has a rocker switch enclosed in
a rubber membrane with a toggle outside the membrane.  I have had one on my
boat for 2 seasons without failure.  West Marine no longer stocks these
switches.  The Cole-Hersey part numbers are c1005-507 and c1006-502.  I
believe the part numbers are for different styles of external toggle
According to the local West Marine store, Cole Hersey's phone number is:
973-887-9400.

Another option to protect the switch is to put it in a small plastic food
container and sealing the wire holes with 3m 5200 or Aquaseal.

I now use a 2.2 AH lead acid gel cell battery and a 500 gph Rule pump in my
primary boat.  The pump draws less than 2 amps.  I presume as a first
approximation that the pump will operate for about an hour before the
battery is drained.  As a practical matter I have yet to drain a battery,
whether on a trip or while practicing various boat swamping activities in a
pool.

The battery/pump combination is a trade off.  The choice I saw was how fast
do I need to have my boat pumped out.  The 1100 clears the boat in about
half the time that the 500 requires.  The 1100 draws about twice the amps,
too.  A 2.2 AH battery has enough capacity for either pump.  Again as a
practical matter since it takes 2-5 minutes to pump out a boat with an
electric pump a 60 minute battery will not be drained unless you are having
an exceptionally bad day.
