Bilge Pump questions

[Trucky]

It finally died, could be OEM but I doubt it. Factory specs call for a 900gph manual with a float switch. I never saw mine until the mechanic drug it out and declared it dead. The parts manual shows it located just aft of the float switch, not further back under the engine where I suspect it had been.

My questions are:

1. Should it be located as in the drawing, next to the float switch?
2. Is it supposed to be somehow secured so it can't move?
3. Is a 900 gph suitable for my 21'?
4. What Brand/Model should I look for? Rule & Attwood seem to be the common ones.

Rule!! Get them on ebay cheap!!!. Change the switch to!!!

I have an Attwood Sahara and the float is built into the pump housing
it is located right in front of the engine.

In my opinion I would replace the 900gph with a larger one at least 1200 and add a 2nd pump of at least 1200gph the 1st one wired as normal to the switch and the 2nd wired to power as a backup to the 1st set a little higher. In the bilge 900gph won't pump out a good size leak from something like a cracked sea water hose. I'd consider 2000gph I have 2 new ones ready to go in the boat in the next couple of weeks.
