Having some trouble pinpointing a Yanmar part number for the send unit. Do you suppose a generic one that has the same threads and appears identical would work ok ?
For example https://www.westmarine.com/sierra-18-5899-oil-pressure-sending-unit-1654888.html?&utm_medium=cpc&utm_source=google&utm_campaign=PMax: GSC>Smart_Shopping>Engine Systems&gclid=CjwKCAjwzY2bBhB6EiwAPpUpZld5u5VWmXO-kLn9IIg1SqW7hBAdkYzcVKY1RsYdWzwrpJcdgRtrPRoCD4MQAvD_BwE
One wonders if there are impedance differences.
