I just purchased some Bilge Pump Cartridge Motors (Johnson Pump
28552)<http://www.google.com/products/catalog?hl=en&safe=off&rlz=1C1GGGE_enU...>
that
I'm going to be using as thrusters on a custom built R.O.V.. I have
searched high and low trying to any information related to the typical
current draw on these things and haven't been able to find any. I was
thinking there might be a small chance some of you guys have tinkered with
replacing these cartridges or for some other reason may have some idea what
I should expect. I'll be able to find out for sure once they arrive but
I'm trying to also order some motor controllers right away and want to make
sure I get ones strong enough to power these motor. If anyone has any
advice or input, let's hear it!

The page lists 1.4 Amps as its normal draw and a 2 amp fuse so if you go
with something around that level you ought to be safe as far as I can
tell. I'm not really an expert on motors though.

Well... I tried but I can't come up with any believable excuse for why in
the world I didn't see the current draw rating ON THE PAGE THAT I LINKED TO
ABOUT NOT BEING ABLE TO FIND THE CURRENT DRAW RATING! (should have slept a
little more last night)
However....
I'm glad that I didn't because I kept searching and found where another
person was using these motors for the exact same purpose I am, and he had
done a TON of experiments to test the current draw using multiple props and
at various water pressure levels. Although he was using a slightly larger
motor (750gph), he was reading somewhere between 4.5 - 7 amps on motors
that were spec'd to draw around 2A. So it looks like adding the props to
the motors does require a bit of increased current. I'm going to shoot for
controllers that can handle around 12A continuous as I plan on going up to
the 1250gph motors very soon.
Thanks for pointing out what was right in front of my face! :)
