I have the same block. One sender is much larger than the other on it. The larger one on my boat is for the oil gauge and the small pancake looking one is for the alarm. If you are not sure which one, take the wire of the large sender and see if you still show oil pressure, if you do not than that sender is for the gauge.
You can buy senders with different pressure ranges on them. The alarm sender can be what ever you want it to be. The oil gauge sender has to be match with the oil pressure gauge or you will get false readings The oil pressure alarm should sound and light up when you shut down the engine If it turns its self off when you restart the engine, than it is working correctly. Make sure you have good grounds (common problem), A poor ground will cause you problems Capt.

So yes, I would expect that yours is near the pressure sender. I don't know your engine(s), so it is possible that they are NOT together, but I'd look there first. Good luck and let us know what you learn.

Our Uni is a 1973 31' Sport Sedan: Been following your oil alarm posts. I have a port oil alarm that rings and flashes the alarm at incorrect time... my ring sounds and light flashes the port oil alarm seconds after the motor is shut down and oil pressure is at 0. I simply flick the alarm master switch to off and on; depending if motors are started or off. But, I wonder if the port alarm would work if oil pressure dropped while motor was running?? Can you tell me where to look for the sender switch in this case? I imagine it's on the engine right by the sender for oil pressure gauge - correct? I've not searched for it yet but plan to locate and replace it in near future. Any hints appreciated!

I have determined that mine is closed at low or no pressure. Therefore it is OPEN at pressure. I glanced at Summit but I don't see anything there, so I will stop in at my local auto parts store.
