My boat does not have an automatic bilge pump so need to switch it out before I go on multiple day trips. Was watching a fishing show were they talked about some which are cartridge based, it if fails you just replace the cartridge not the whole unit, this is a pretty good advantage. However, I am not having any luck finding them online. Anyone got any ideas on where to find them and/or suggested model?

AMAZON. Rule Bilge Pumps

I'm not sure if you're looking for a pump with the switch built in or not but I don't think you can get those in a cartridge style. You can get a cartridge style bilge pump and add an external float switch though, or add a float switch to your existing pump.

The fully automatic pumps are sealed.

Okay...was worth a shot. Will look for a auto one that fits in my rt188. Some have a longer float arm that does not look like they will fit.

Rule makes more than one Automatic that is not sealed

If I am correct,  Rule pumps cycle themselves constantly checking for water. Do they not?

Lots of options out there.  I went with a set up where the motor/impeller is removable from the housing, so if he motor dies there is no need to pull out the thru- hull housing or undo any plumbing/clamps.  Further, my livewell fill pump uses the same motor/impeller, so if the bilge pump dies at an inopportune time, I can pull off the livewell motor/impeller an install in the bilge pump housing (I used waterproof connectors to wire everything up so it is all plug and play.  Mine is manual, my boat is never going to be in the water when I'm not in it, and I figured if its taking on enough water that I need a pump to automatically purge it out, I aught not to be on the water till I get the leak fixed.

 

Here is one that has the float built in, so nothing to remote mount.  Solid state too, so no pivots or contacts to go bad and give you a nasty surprise.

I have a standard Rule on a Rule Automatic switch it never runs until it gets water to trigger it.
