Question Yamaha Fuel Management and Engine Warranty

Does anyone know if the Yamaha fuel management sensors/sending units are covered in the 2 + 3 year extended engine warranty? My starboard engine (200 HPDI) fuel flow is indicating a dashed line at all rpms but the engine is running fine, no indication of it being a true flow issue. Port engine running and indicating fine. Any other suggestions besides the fuel management sensors? Engines are still under the extended YES warranty and it would be nice if the sensor, if its failed, is covered...

Thanks!

Auburn,

Are these Command Link gauges or regular multi-function gauges?

Andy would know better than me, but I went through this 2 years ago. Was told the sending units were only covered for a year. I was told that they are part of the fuel system, not the motors. They cost about $300 each.

They are the regular gauges, year 2005. I let the boat sit for about a month due to work, went out yesterday to run the engines and found the one input failed. Its true that a boat doesn't like to sit unattended for long...

I've heard about $300 for a new sending unit...ouch.

They are covered for one year - probably the connections at the sender

Gauges are covered for one year unless the boat is Power Matched. Then, the gauges follow the basic warranty. Sounds like you are out of warranty in any event.

Have you confirmed that the sender is definitely bad? Swap the connectors from one sender to the other and see if the problem moves to the other motor.

Wish it was that easy. THe dealer told me that they never had one of these go out. Well I bought a new one $300 put it in and it worked for one day. Brought it back and they couldn't believe it. They actually gave me a hard time about getting a replacement. Well the replacement has been in for 2 seasons now with no problems.

Thanks for the responses; accurate they were. I verifed with the dealer and Yamaha that the fuel management sending units are covered for only a year and that the YES extension is only an extension of the second year's coverage for the HPDIs. But on a better note, I checked all wiring and its all very stout, sealed in tightly to the sending unit and the back of the gauge. Played with the wires, agitated the connector at the unit, ran the engines again. Revved the starboard up to establish higher fuel flow and indication came back normal at all ranges. Not sure whats inside that sending unit but if its a spinning wheel it might have been slightly stuck. Anyway it seems problem solved for now.

It's a spinning wheel. Keep an eye on it, cause mine did that for a while then went dead.
