Yanmar 6LP temperature sensor

[jms02050]

Hi -

Looking for info from anybody who has replaced the temp sensor on a Yanamr 6LPA-STP. My boat is an 03.

I have a Beede combo gauge. Appears to be model 945731 10-02-02.
I was able to pull the following numbers from the existing sensor: 0655-7338.

I found that the sensor is bad by grounding it out with the ignition switched on and the temp on the gauge pegged as can be seen in the photo. The gauge had been stuck at 165 which led me on this journey.

Called a local Yanmar dealer to no avail. They couldn't determine which sensor.

I talked to 2 Yanmar mechanics hoping to source the sensor/sender:

The first mechanic said it's a custom VDO gauge made for Albin. That doesn't make much sense to me unless Beede rebranded VDO gauges. No luck with him.

The second mechanic who services the engine annually said it's a custom sensor from Beede and he'd need to try to source one through them.

Does anyone who has replaced the sensor have a part number or source? I can't imagine it's this tricky to chase down this part but no luck so far.

Hello. I just found your post while scanning the archives. I have the same set up. Were you ever able to source a replacement sensor? Thanks!
