Now that's why I joined CSR!! Out today on Pittwater with friends, alarm goes off and smart craft says "water pressure sensor" or similar (several hours later as I'm posting this). We had only been doing about 4 knots and alarm sounds and "guardian" kicked in. Engine temp normal as were all other gauges. I turned engine off to open hatch to inspect but it wouldn't let me start again. Drifted over to a moored yacht and tied off, made some new friends!! But jumped on CSR on my iPhone and found this wealth of information.
After reading this thread while tied off, I disconnected the plug from the sensor. Engine was clearly not overheating. Started fine and we then limped on, sensor disconnected. All gauges remained normal. Got up onto the plane and 10 minutes later at 3600rpm alarm sounds again. Throttle off to 2000rpm alarm stops. Spent a lazy afternoon on a mooring at The Basin and then engine wouldn't start. Reconnected faulty sensor and started fine. 5 minutes later alarm sounds again and guardian kicks in. Stopped, disconnected wires from sensor and started again, away we went, all gauges fine, certainly no overheating issues. Alarm sounds after 10 mins on plane at 3600rpm, throttled back alarm stopped. Didn't interrogate smart craft warning at this point as I was watching the gauges while throttling back and then alarm stopped. We just came home then at a leisurely 2000rpm.
Im hoping this is just the faulty sensor I've now read so much about here but my question is, are these other symptoms consistent with just a faulty sensor? Guardian kicking in, another alarm after running 3600rpm for 10 minutes, not wanting to start again after being off for several hours, mind you when we stopped we turned engine battery off - this might affect restarting if there is some sort of resetting going on once engine is turned on or off. Anyway, any knowledge on this would be greatly appreciated.
