2008 bilge pump on r25

what brand is the bilge pumps used on 2008 r25? The one just after the engine under the drive shaft sometimes does not stop running after the bilge is pumped out. I think I should get a spare.

I had this very problem today. It seems after you give your bilge a good flush, the pump is likely to get plugged up - it then keeps running without pumping - the way to stop it is just suck out the bilge with your shopvac, then the pump will go silent. Then you have to unplug things. You remove the barrel of the pump by pushing the little black lever at the back aft, which allows you to unscrew the pump and lift it out it's housing (still attached to its wires). You can see if it or the inlets at its base are plugged, and give them a flush (keep that shopvac handy).
If the pump still does not work, the hose pipe leading to the transom is plugged. Sounds daunting, but just remove the hose close to the pump, insert your water hose in it, and flush it, until you are sure water is coming out the transom at a good rate (it's good to have a helper).
The pump on my 2008 R25 (and I am talking about the pump in the bilge, just behind the transmission, under the prop shaft), is a Johnson 1250 GPH cartridge type centrifugal pump.

Thanks, I'll try what you suggest. However I think I will get another pump as a spare.

If you have the electronic sensor that can also be the culprit. After you clean the impeller on the end of the pump and make sure nothing else is clogged make sure the sensor is clean from grime. There are two round circles on the sensor. Touch those with two fingers like you are making a peace sign. The pump should engage and after removing your fingers it should go off. This should be checked on a regular basis.

The pump is a Johnson 750 GPH cartridge pump. You don't need to buy the whole pump, just the cartridge. You can check it out at this link.

You can buy a replacement cartridge from the Ranger Tug factory for less money than most of the online sites I have looked at. On the Tugnuts home page there is an attachments column on the left hand side of the page. Click on the R25 27 attachment and follow the instructions or simply call or e-mail Richard in the parts department.

My 2008 R25 bilge pump did the same thing, failed to shut down after pumping. Turns out it has a float switch, it's a little floatie thingie under a kinda hood. So it was sticking in the "up" position and upon exam, was all goobered up with moss and slime. Changed it out and things are fine. On an odd note, when the pump was doing it's "keep running" trick turning the pump switch on and then off at the 12 volt panel in the cabin would stop it.
