|I have a 99 Maristar with a yellow and black bilge pump, the pump is a cartridge type with a square float device. When in the Auto mode the float will not activate the pump, either by hand or when we get a little water in it. It does work when I flip the switch to on. I would get the brand of it, but it is at the lake, which is two hours away. I am trying to get the make of this so I can get the float switch and replace this weekend as it will be on a buoy for a week. Any help is appreciated|
|I'll be at my boat tomorrow (same boat, but '98), will try to take a look to get you what you need to order a new one.|
I think this is what you need. Pretty sure its a Mayfair bilge pump. Couldn't figure out exactly what the GPH was, but guessing 750. Hope this helps, good luck!
Here's a link to one on the web...
