Whale Supersub automatic bilge pump?

Apr 28, 2005

Anyone have any experience with this automatic bilge pump? Looks like a good option for the bilge in my O'Day 302?
Have a manual Rule pump now - looking for something that is automatic so I don't have to keep returning to the boat to check the bilge after the monstrous rains we've been getting this summer. Thx. in advance.

Check the reviews in Amazon 3 stars out of 5 on 29 reviews. Check the size of your discharge hose. If your Rule pump is still good consider just adding a float switch.

You can:

1. Convert a non-automatic bilge pump to automatic operation by connecting the pump to a separate float switch. These switches consist of a hinged float that completes a circuit to energize the pump when the bilge water rises.
2. Or replace pump with an automatic bilge pump with a built-in or external float or electronic-water-sensing bilge pump switch.
