2013 Sante 210 speedo and bilge pump issues

[rickc]

I'm having issues with my speedo showing either 0mph or jumping up and down (even when not in gear) and not keeping set speed when speed control is on in any pre-set mode. Also, the bilge pumps keep shutting down (blinking bilge pump light on console). I have to completely shut down and restart to clear the blinking bilge light. After short use, it shuts down again. Speedo works when speed control is not engaged. Had service this spring. Dealer said Linc 2.0 was set for a 200 and resetting for 210 should fix issues. Previously, I went to a different pre-set and it would work. Two days ago, all pre-sets had the same issue with engine and speedo surging and bilge pumps shutting down. Not sure if the two issues are related, but both started on same outing last year and continue now and is getting worse. Dealer could not duplicate problem so another trip there won't help since it only happens when out on water in use. I've tried to duplicate on land, but can't duplicate. Anyone else have this issue or have any suggestions on how to fix? I'd rather not replace the GPS pod ($1K) or new Linc 2.0 ($5K) trying to guess since it might be a wiring issue. I'm not technical, hoping for some guidance on next steps. Any help would be appreciated.

When this speedo thing happened on out 2014 210 it was the paddle wheel. The blinking bilge light issue was needing a new set of bilge pumps. Happened at different times on my boat.

I have been having the same bilge issue as you on my 2012 230. Dash bilge button starts blinking and bilge stops working, shut down completely and bilge will pump again. I do not have Linc so I think you can rule out that being the issue with your bilge. I just pulled my rear bilge apart and there was some junk on the screen. Cleaned that up good but haven't been back out again to test if that solved the issue. I will report back after this coming weekend.

Follow-up: Dealer replaced front bilge pump and updated keypad (they said they are finding if one bilge pump is replaced to a newer model pump, then it confuses the system and both should be replaced at same time if replacing with a newer model bilge pump). Also, dealer found heater box was spraying water and steam under console, directly under GPS pod. Dealer replaced heater box. Had the boat out yesterday. Bilge pumps worked without shutting off (blinking light) and GPS cruise control worked perfectly, on all presets. Looks like the heater box was causing the GPS/speedo issues. Glad to have issues gone and enjoying the SANTE again!! Thanks for the feedback from the two responders. GO Nautique!!!
