High oil pressure problem?

The oil pressure gauge for the PCM 351 in my 76 SN says my engine is running with 70-80 lbs of oil pressure. This seems high to me.

Got my 76 out on the water for a weekend of running it and trying to become intimately associated with the boat (only had it a month and this was the first chance to get it out on some water). Have had a chance to go through the basics while in my driveway which included new plugs/wire/cap, new raw water pump, oil change, exhaust tubes, battery and connections, and wired a new bilge pump along with some other miscellaneous items I came across while delving into my new toy.

From all the info I gleen from you guys, I feel that the OP should be somewhere around 30 when cruising, up from 10-15 when at idle. Feedback?

Due to a lack of time I had a local shop do the oil change when I had the water pump replaced, so I don't know what weight he used. I assume it's a the recommended weight but I can't confirm. I'll have to check the invoice. In the meantime, I'll follow your recommendation about the stuck switch.

Scott,
The pressure bypass is not a switch as in something electrical and not related to the gauge. It's a spring loaded mechanical valve. Get the gauge T'd in and report back.

I didn't really notice a fluctuation in pressure, it seemed to stay high all day long when in use wether it was warmed up or cold.

I would call the PO & ask him about it. Not to complain, but to find out what he might have done.    Maybe he installed the wrong sender.

I'm not ignoring you guys, I just haven't been up to the lake for a couple weeks to go over the boat. I'll check back with an update when I head back up in a couple weeks. Thanks for all the suggestions.
