Rule brand or Johnson Pumps both have good reputations. (I have both on the 3000)
Pump capacities are always misleading unless you look into the conditions the rate was based upon. This includes the head, or distance the pump has to lift the water and the hose diameter.
I believe in a dual setup, with a smaller pump located low in the bilge for normal dewatering, with a larger high capacity pump mounter slightly higher for emergency situations. Two Johnson 750’s handle the smaller pump duties in the mid bilge and the ER. Large pump for the mid bilge is a Rule 2000 and a Rule 3700 for the ER.
All have Rule float switches and are hardwired (with fuses) to the batteries.
