TROUBLE SHOOTING VOLVO MD11C 25 HORSE MOTOR

I HAVE A VOLVO MD11C 2CYL MOTOR IT HAS A PROBLEM WITH THE OIL PRESSURE
WHEN I START THE MOTOR IT SHOWS NO OIL PRESSURE AND THE OIL LIGHT IS ON IF I RAISE THE RPMS TO 1800 OR HIGHER OIL PRESSURE IS PRESENT IF I
LOWER RPM IT GOES BACK ON AGAIN. THIS MOTOR HAS NO OIL DIP STICK AND THIS MAKES ME NERVOUS WHEN IM SAILING ON THE WATER.

Do not run this engine. Much damage can be done. There appears to be quite a bit of oil by-pass going on. If this was sudden, could be as simple as the oil bypass relief valve.
If it leaks it may only give you some pressure at high RPMS where the amount of oil being pumped is larger than the bypass leakage rate.
It is best to have a mechanic look at it or if you familiar with the engine mechanics, take a look for a bypass relief valve.
