Have Boat Questions? Ask a Boat Repair Expert.
Hello my name is ***** ***** am I speaking with?
Which tachometer do you have installed in the boat, is it a Yamaha tach or another brand?
What color wires do you have hooked up to the back of the tach?
What is the model number on the engine?
Do you have a voltmeter, and do you know how to take voltage measurements?
Are you near the engine now and ready to work?
I would need the exact model number to continue. Without it I dont' know which manual to pull. There are no time limits here, do you want to reply back one you have the model number?
Got it. Hook your meter up to the battery, start the engine up, and bring the rpms up to about 1500. What does the voltage read?
You have to be able to run the engine in order to test this. What kinds of questions did you have?
The tach gets it's signal from the ECM, which in turn gets its signal from the voltage regulator. The voltage regulator is a portion of the battery charging system. So what you want to do is see if the battery is charging or not. If it's not, then the voltage regulator is likely dead. If it is charging, then there is likely a short in the tach output circuit board inside of the ECM. And at that point you would either get a new ECM. Or, get a basic cheapo tachometer and hook it up to the voltage regulator. does that make sense?
Did you have any further questions on the issue?

Hi. It looks like you read my answer without replying back or leaving a rating. Please keep in mind the website has charged you to speak with me, but they will not credit me for helping you until you put through a rating for me.

Thanks again and happy boating!
I'm sorry I don't understand you. Why are you telling me wiring colors?
But I don't understand what you are trying to do??? Are you trying to hook the tach up? I thought you said you already had it hooked up?
