Now What????

[res1xhxc]

Well, I'm back on the water finally! Lightning strike in June had my head spinning. After replacing 1 ECU, the entire ignition system and both tacs. Grady is running fine however, the engine temp. & oil pressure warning symbols on ttbd tach are bilnking all the time engine is running. Oil level is on the mark and she is spewing full stream from the "pee hole". Any ideas?

It would help if you would post some motor and tach info as no one knows what you have.

Is the problem on the motor that you replaced the ECU on or the other one?
I would think the info comes from the ECU to the tach but I am not real sure.
could be sensors bad going to ECU also

If these are the Yamaha multifunction digital tach then may not have dip switches set correctly for your motor.

Tacs not reading

Thanks Boats.net, now have new tacs (6Y5-8350T-82-00) and they are working... however the stbd tac is showing blinking temp/oil symbols so I will check dip switches today.
It's getting better!

Yep had a lightning strike on my 26' Grady 8/7 with me and the wife on the boat. My insurance company totalled the boat. Did you have insurance. Yam tech said my engines will never be right.
