Would anyone be able to send me down the right path for diagnosing the alarms I'm getting? What put me onto this forum is some of the valuable insights shared about similar issues. For context, I bought this boat used on a whim, in July 2025, after the owners (who inherited it short vid 1 https://drive.google.com/file/d/1oYpHGVn2d7E2nRrA4V-aExk2_JSfW5e0/view?usp=drive_link short vid 2 https://drive.google.com/file/d/1mRd3qiIBCjeULX5sExcyvMShdQzHAjyp/view?usp=drive_link |

I can't say for sure what those alarms are, but I do have a solution for you. I have a 2001 Horizon 180 that started giving me alarm signals. In my case it was a low oil pressure alarm, and it drove me crazy. The engine never suffered low oil pressure, and it wasn't the sender, it was the VDO dashboard. These dashboards are notoriously unreliable, and virtually unrepairable. Supposedly they are made like automotive dashboards, and just didn't hold up the the higher moisture environment on a boat. A few lucky owners have found a solution by adding an additional GND wire. I was not so fortunate. In my searching for a solution, there's really only one way to solve this problem - replace the dash cluster with individual marine-grade gauges. Once upon a time, someone was making a plug-and-play dashboard that used all of the original sensors, but consisted of individual gauges that were assembled into a wood cluster that fit into the dashboard shroud. Alternatively, you could source your own gauges and assemble them as you want - be with this scenario you need to pay attention to whether the senders on things like the speedometer and trim gauges are compatible, otherwise you're running new sensors and possibly wires. In my case, I yanked the alarm module off of the back of the computer board behind the dash. My oil pressure gauge will often read "0 PSI", but I ran a separate mechanical oil pressure gauge, so I know it's the cluster and not an actual problem. |
