I have 2006 Stingray with a Volvo/Penta 3.0. At idle, oil pressure reads 0-5 psi, so the alarm is going off. WOT it reads 30. I changed the sending unit and sensor and it still continues. Is the gauge bad, oil pump going or some other issue??

Since you replaced the sending unit my guess is you have an oil pressure issue and that would be related to a worn engine or incorrect viscosity oil. To know for sure with pressure you need a mechanical gauge which you can install where the sender is. What weight of oil are you using and when was it last changed with filter?
Oil level is normal
I hooked up a mechanical oil pressure gauge and the pressure is fine (50PSI at 300rpm). So, Is the gauge bad or maybe a wire?
I replaced #15 and #16 which is listed at sensor and sending unit. Is that what you are referring to as the sender? or is there another switch/part that I missed?
I replaced both of them and still have BS readings on the gauge.
