Qsb5.9 oil pression

[John]

Good morning,

Port side oil pressure is about 12 @ 15% more than starboard.

3.40 vs 3.04 This has 2800 rpm

Oil pressure difference

I also experienced this. QSB 5.9 380hp. 2650 rpm cruise,  port side 43.5psi, stbd 48.1. Everything else was normal. At the time I chalked it up to a minor measurement/sensor error.

BBased on what Tony said I guess it’s ok.

Remote mounted oil filter ???

Is the oil filter on your starb engine remote mounted?  If so, this is probably the reason for the lower oil pressure compared to the port engine.  I had a similar discrepancy on my previous boat which was fitted with QSC600 engines and once I removed the remote set up and mounted the oil filter directly on the engine, the oil pressures were the same, give or take a few psi.

You are well within tolerance–Normal to see differences like that between all engines/gauges
