M6 high oil pressure


Recommended Posts

200523lsv

Recently changed oil in 2020 25lsv M6. Oil pressure is now reading 60 psi at idle and 80 on revs. About to leave town for memorial weekend. Boat has not thrown codes on fake a lake in the driveway. Should I be concerned with such high pressure? Oil level is accurate and used Malibu 5/30 oil and wix filter. Thanks guys. Need answers quick please 🙌🏼🙌🏼

Sounds fine to me for cold pressure.  What was it reading before?

My 2012 5.7 still puts out around 80psi at high revs hot or cold.

Thats the problem is I don’t recall the oil psi before. Boat is new to me. Came from a 2013 350ss which never read high like this

Then your engine was likely wore out ;)  My 2012 350SS puts out that kind of pressure.

Don't worry - go boating

My '06 23LSV jumped to about that level of oil pressure last summer.  Boat ran fine and performed exactly as it did when the pressure was lower (around 50), but I was concerned as well.  Everything I read and everyone I spoke to about it said that high oil pressure is almost never a problem - low oil pressure is what you would have to worry about.  Took it to Powell for a week after that, and probably ran about 50 hours on it since.  No problems at all.  For what that is worth.....

From reading you're post it sounds like you are running it in the driveway on a fake lake.  If the engine water temp is not up to normal (165) then 80 would not worry me.  IF the engine was at 165 then something would be wrong.  Wrong could mean bad sender which would not keep you from going on the lake.  Odd case would be something obstructing the flow (trash in oil passage) resulting in higher oil pressure and lower flow = poor lubrication, likely engine damage.  Never heard of a bad filter that would not pass oil, guess it could happen (did the filter have a plastic film to keep dirt out that got left on?).  99% chance when your engine and oil are warm pressure will drop.  Our 2021 M6 runs 58-60 pounds surfing.  

 

One more thought.  It is much more likely that if this is a hot oil reading that the reading is wrong not that you have an obstruction and so poor oil flow.  At that point to be sure you would normally use a mechanical gauge to verify.
