xwillyumx Posted July 20, 2015 Report Share Posted July 20, 2015 Had my boat docked this weekend, came back the next morning and found the bilge light was on, but the switch was not engaged and the bilge was not on. Flipped the bilge switch a few times and nothing happened, and once i pulled the drain plug after trailering, the light turned off. Pretty sure I need to replace the bilge pump, I have the S500 Sahara pump which came with my 2013 F21. Anyone ever changed their's? Looks like it would be a simple plug and play after buying a new pump, which is only about $40. Quote Link to comment Share on other sites More sharing options...
oldsmobiledriver Posted July 20, 2015 Report Share Posted July 20, 2015 Was there any water under the bilge? Sometimes there is just enough water under mine for the float to turn the light on but not the pump. Quote Link to comment Share on other sites More sharing options...

oldsmobiledriver Posted July 20, 2015 Report Share Posted July 20, 2015 With the shaft seals in these MB's you always want a working bilge when the switch is on. They need a on position and a MB shaft seal on high position lol SkySki and M1AHD 2 Quote Link to comment Share on other sites More sharing options...
grantschim Posted July 20, 2015 Report Share Posted July 20, 2015 That seems kind of soon for the pump to go out doesn't it? Have you contacted MB? Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

xwillyumx Posted September 21, 2015 Author Report Share Posted September 21, 2015 just now saw these replies, headed back to the lake house this weekend, and got a new bilge on amazon just in case (it was only $35). Seems like it should be an easy switch out yeah? anyone have any experience? Quote Link to comment Share on other sites More sharing options...
M1AHD Posted September 22, 2015 Report Share Posted September 22, 2015 It's as straightforward as it seems... If you have a multimeter bring it with you. I would check for 12v at the pump when you engage the switch before pulling out the old pump. Just to verify it is the pump that died, and not a electrical connection/wiring problem.

alexisss Posted July 4, 2024 Report Share Posted July 4, 2024 You definitely dodged a bullet there! Finding the bilge light on with the switch off is a cause for concern. Sounds like your bilge pump on that 2013 F21 might be kicking the bucket. Replacing the S500 Sahara pump shouldn't be too tricky – from what I've seen online, it seems like a pretty straightforward swap. Here's what I'd do: 1. **Double-Check the Fuse:** Before you grab a new pump, there's a slight chance it could be a blown fuse. Check your owner's manual to find the bilge pump fuse location and verify it's not toast. 2. **New Bilge Pump Time:** If the fuse is okay, then yeah, a new pump is likely the solution. The good news is, like you said, the S500 Saharas are affordable, and replacing it sounds like a plug-and-play job. Here are some additional things to consider: * **While you're at it:** Since you'll be messing around with the bilge pump anyway, it might be a good idea to check the bilge pump hose and any connections for wear or cracks. * **Take your time:** Even though it seems simple, don't rush the replacement. Take your time to ensure everything is properly connected and secure before putting the boat back in the water. There might be some resources or videos online specific to F21 bilge pump replacement. You could try searching for "[F21 bilge pump replacement]" to see if anything pops up. Good luck with the swap! Quote Link to comment Share on other sites More sharing options...

Spencer Elliot Posted December 28, 2024 Report Share Posted December 28, 2024 It sounds like you're on the right track with the bilge pump replacement! If the bilge light came on but the pump wasn’t running, and the light went off after pulling the drain plug, that’s a good indicator the pump might be stuck or not functioning properly. Replacing the S500 Sahara pump should be a relatively straightforward task since it’s typically a plug-and-play setup. The only thing you might want to double-check is the wiring connections and the float switch to make sure it’s all in working order when you install the new pump. It should be a simple fix, and $40 is a pretty solid price for a new pump. Just make sure everything is secure once you replace it, and test it out. Hopefully, no more bilge light drama during your next trip! It's kind of like the feeling you get in driving games when everything finally works smoothly after some troubleshooting—satisfying once it's all dialed in.
