Mercury optimax 225hp sensor fault
I have the above engine with three faults on the smartcraft gauges. I'm getting there re fault finding but could do with some help
First one is fuel fault. There is no sender from the tank, sometimes it reads 93litres in the tank, other times it faults. Can I bypass it altogether?
Second one is trim fault. I've located the trim sensor and have yet to check the wiring. If the sensor is stuffed any advice where I can buy one? Engine is a 2001 with a warranty replaced 2003 power head
Third one and most annoying is a water temp alarm. After a lot of reading I've discovered that this is an outside water sensor to let the ecu know when the water is freezing etc so it adjust oil mix etc. I think it's this one that sets the alarm off 4 beeps every 2 mins arghhhh
I don't know where this is on the engine I assume cylinder head? If anyone can let me know where to look that would be fab and again if it's not wiring where to get one?
Motor has been stored and is now back in use which is where the faults are coming from. Runs and pumps water fine so I'm fairly sure this is just annoying stuff
