Morgan Catalina 45 CC Kemah
I bought a Morgan 45 cc with dual Racer filters, the type that is switchable so I can change filters while still running the engine.
The filter has a gauge on it.
My question is : what pressure reading do I need to switch from one side to the other to change the clogged filter?
I don't have any operating instructions and can't find any on the internet......even from the Racer site.
Many thanks.

Vacum Guage

I'm not sure that the actual numbers are very important. Will vary from boat to boat, and guage to guage. You need to know how much vacum you are pulling with a known clean system and new filters. Should be very low. Then watch, and when the guage starts showing increased vacum, you know the filter being used is about ready to change. By watching closely, you will soon know at exactly what vacum reading you need to switch out.
