"The problem here is that the pickup tube doesn't go all the way to the bottom by design. It usually has an inch or so of clearance. Now, let's say you have a half an inch of water in the tank, all is OK until you bring up the bow. Now that half an inch becomes 2 inches and water starts to get sucked into the motor. the only way to pump out the water is to go in the tank with a pump and make sure it pumps from the bottom"
That's not necessary--- Raise the motors all the way up and then raise the bow by jacking up the trailer as high as possible. This may require placing a support under the trailer tounge and re-raising the trailer with addition supports under the jack! That should push almost all the water that may be in the tank to the area around the pick-up tube.
