Sep 27, 2011· Yanmar, however, uses a proprietary sending unit, which meant that I had to replace the sending unit and the oil pressure gauge as a matched pair. I ordered a Teleflex gauge model 80180P at 0 to 80 psi and “C” sender from Defender Industries for a total cost of $63 plus shipping, still cheaper than a new Yanmar sending unit alone.

Jul 13, 2019· The Yanmar 6BY2-260 is made by BMW and Yanmar converts it to a marine engine. In that process, an engine oil pressure sensor located below the oil filter and pretty much out of sight, is not being used in the marine application. That sensor had unscrewed itself and the oil pump just ejected all the oil into the bilge.
