Put a mechanical gauge on it and make sure it's not a gauge problem.
Don't run it any more until you know. It won't make any unusual noise
until the bearings are shot and then you get to rebuild it again.

I have a recently rebuilt Unversal 5418 two-cylinder diesel. My
mechanic started the boat last weekend and noticed there was no oil
pressure. The engine runs and sounds just fine.
Has anyone ever had this problem? Any experience ? Should I curl
up in the fetal position? I just spent 4,000 to have this engine
rebuilt.
