Yanmar 3QM30's oil pressure switch location?

Hi folks,

This model Yanmar is new to me and we are starting to get to know each other. I am not able to locate the oil pressure switch that activates the alarm and light on the engine panel. The oil pressure alarm didn't work when I purchased this boat, and I'm going through the engine in preparation for our upcoming cruise.

If by some chance there isn't a oil pressure switch on this engine, has anybody found an appropriate port to install an oil pressure switch?

Many thanks,

Marc

As a matter of fact I just replaced mine this year. It is located just aft of the oil filter.

Thank you Frank! I will have to get a mirror and look for it, or get down into the port lazzarette.
