BTW - if you do test it (including power draw with a VOM), compare it 
to the rating for the pump.  IIRC, the "standard" for rating is 
pumping against a three foot head.  Since a kayak should have less 
than a one foot head, this will give you an idea of the rating's 
accuracy and you can adjust your battery size accordingly. It helps 
if you have a source (old car battery?) to test with before plunking 
down the money for the real battery.
