I'm a bit late in this discussion, but that's how I am. I'm a quiet guy
.however I think I should come with a warning about placing the bilge-pump too high up from the bottom of the boat. (the cockpit level is too high)
Most pumps are really bad at sucking air, and that's what the pump has to do before the water can rise inside the hose.
It should be placed as low and as close to the water as possible so it "prime" or fill with water easily.
I placed mine under the port seat just opposite of where Boat has suggested in the drawing , low and near the water.
Pushing the water out on the discharge side is easy and You can go as far and as high as You want on a small boat.
To illustrate this, a perfect vacuum is 1 bar and it would suck water 10 meter up to the pump max.
We have pumps here on the job that creates 740bar pressure on the discharge side and that would push water 7400 meter up in the air.
as where Mark wants to put it I,d have to think it,s with in the pump,s capacity so should not b an issue , I,d not b going with the one Mark choose as mentioned earlier u want a removable handle as when attached u r gonna get at least 3 times more leverage with an end result u r gonna b able to pump 3 times more water if necc.
