High Oil Pressure from Mercury 377 Scorpion Engines

I recently purchased a used boat with twin Mercury 377 Scorpion Engines with approx 200 hours on them. I noticed the oil pressure on both engines run approx 75 to 80 psi at 3,000 RPM. Is this normal for these engines?

It seems a bit high as I'm used to the Mercury 454s. Also the boat has new Livorsi guages thru out.

Does anyone have any experience with these engines?

Are you sure you have the correct ohm senders for the new Livorsi guages????

How would I go about determining the correct ohm senders for my gauges? I have very little experience with installing gauges.

Fixed - wrong sender - thanks Griff.
