I took the boat out last night and after running under load for about
15 minutes the engine in question started to lose oil pressure.

At once I shut the motor down.

I'd start by changing the oil and filter one more time and ensuring
that you use straight HD 30 weight oil. Those are hard working
engines and multi viscosity oils like 10W-30 can be a problem.
