Review on 🚿 High-Quality Water Pressure Sensor Switch Sender, Replaces 8818790 for Mercury Quicksilver Mercruiser Mariner - 8M6000623 8818793 by Rip Twin

So far, so good! good for spares

I bought this for our 2004 Sea Ray 220 (5.0 Merc MPI) after I noticed my water pressure was 1.6psi and it started generating alarms for sensor failure. I knew the water impeller was new so it wasn't the problem. The installation took me 5 minutes. My water pressure immediately dropped from 1.6psi to 36.7psi. No more mysterious jamming signals. Problem solved!
