No reading on oil pressure guage

I have purchased a new to me boat with twin 7.4l 1996 Mercuisers. My Starboard engine is showing no signal on the oil pressure guage. I have pulled the dash to check for inhooked wires to start but see nothing of issue. What are some ideas for the next step on diagnosis. I would like to handle this myself and not waste the money on a mechanic for a possible simple fix. Thanks

Ayuh,.... Pull the wire off the sender unit, 'n ground it out on the block,...
The gauge should Peg, High...
If it does, replace the sender....
If not, replace the gauge...

provided the gauge Is in fact powered when the key is On..

Btw,... I plumbed in a mechanical gauge at the motor, off the oil port beside the distributer...
