Oil Pressures


board brained

Recommended Posts

have the 320 LCR, I am seeing oil pressure around 47 psi at 1000 rpm and around 75 (give or take) at 3000 RPM......

this is in the correct range...yes?

reason I ask was i was looking at the engine manual and it stated psi range from 6psi at idle to 80 at high rpm.... the low end seems to be alot lower than what i am seeing.

thanks

I have an 04 LCR I see it anywhere from 6 at idle when at operating temp to 60+ when it is just warming up. The best thing to do is find out where you boat will be and when. Your motor may not match mine on oil pressures but is will be very consistent to itself. Watch what your motor does and when Temps time on the oil ect. then you will be able to know if you have a problem before the alarm goes off or before you get to the oil change because there was a change in behavior of the motor. Its called "trend monotering" in aviation and the basics can be used on our boats as well. just keep an eye on what is going on and look for any large change, or exceedence from the norm.

I actually had some questions on this as well. I just picked up a 04' Wakesetter LSV 23' with the Indmar Vortec HO 8100 engine and when the boat is in Idol the Oil pressure light is lite.. but the moment that it is throttled the slightest bit the light goes off.

The oil level looks good and it is not due for an oil change. Is this a normal characteristic of the boat? The light says to turn off the engine immediately when light goes on. Does anyone have insight to this?

So I have the same boat and engine as you do,8.1 in an 04 23LSV with 630 hours on it. My oil pressure fluctuates between 60 and 80 psi. I run 10 quarts in it and use Delo 400 straight 40 weight.

agree, mine has always been around the 40 / 47 at 1000 and up in the mid high 70's during 3000 rpm range

it is funny how you pay attention to it more after you do your own oil change Wink.gif

I have never had an alarm and motor runs great so hopefully I have missed nothing
