oil pressure

I'm getting a low oil pressure signal on my Cat 3116 starboard engine and it's shutting down my engine. I know it's not the sensor because I swapped the sensor with my port engine and I still got it on the starboard. Also, I know I don't have low oil pressure because I clear the alarm and...

I just bought a 97 175 5 series and some of the gauges do not work. I can not find any links to fix this. Oil pressure and up/down gauges do not work. The tachometer works, but can reads high intermittently. Speedometer seems to be a few mph short of my cellphone GPS. I am guessing I have a...

Hi All, Twin ‘98 7.4 454 Horizon Engines looking for some general suggestions on what to check as my port rpms are jumping around a good bit. Not at idle but at running speed up to 400 rpms up and down. Starboard maybe 100 rpm fluctuations. Not sure if injectors are all original or not but...

I have 2000 210 SeRay Sundeck with a 305 Mercruiser, what is the norm for oil PSI reading on the panel gauge at crusing speed?

Hi everyone, Just wondering what other 190 Sport owners with the 4.3 MPI are observing their oil pressure level to be? Mine is normally around the 60psi mark most times, just wondering if that is normal. The Temp normally runs around the quarter mark. Thanks in advance. TopShelf

My oil pressure gauge began fluctuating on a recent trip. It has since gotten worse. I made a 7 Mile trip without having a constant oil pressure reading to get into the dock last time out. Engine sounds fine, now power loss or signs of problems, but scared me pretty good. Thinking of...

Need some advice from the group...since changing the oil in my port engine (Mercruiser 454) The oil pressure tends to drop to around 25 after the engine warms up. It will occasionally go up above 30 and then drop back down to around 25, for no apparent reason. However, the engine seems to still...
