Oil pressure question

What's an average hot oil pressure for my 94 prostar 190 with the lt1 734 hours
Hot I'm running 18 psi at 6-700 rpm idle and 40-45 psi at 30-35 cruise 160-165 hot temp
Boat runs perfect but are these good numbers

Matches what I see out of my '87 with a 351w.

Dunno if it's good or bad. But in all my years with engines... if it's got more than 5psi at idle, and comes up to 40psi under load - you're golden. Some engines run slightly different numbers... but I'd say you're in the ball park.

Oil Pressure at 2000 RPM 18 PSI (124 kPa) Minimum - Hot

Sounds like your just fine...
