It is an oil injected engine.

u sure about that?

Maclin,

by oil injected I assumed he meant 4 cycle. Yeah the engine is a 4cycle Mercruiser 5.0 MPI fuel injected.

When I said "He posted" earlier I was talking to knightgang, so you are the "He posted"...The reason I posted that was knight's response indicated he was giving advice on an oil injected 2 cycle engine which has little bearing on this case. A 4cycle engine is not oil injected.

Guy, don't buy a sensor, that's like throwing money at a problem, eventually you might guess right. Smart thing is do the diagnostic & fix it right without guessing which parts are bad.

You almost have to wonder if it isn't a bigger issue like an oil pump ready to lay on its back with its feet in the air. I agree with NHGuy and go spend the money on diagnostics rather then $100 on a sensor you aren't even sure is bad. That or go buy a pressure gauge that can go where the sensor is and see what the pressure really is and then find out what it should be. If it's up to par, then I'd bet money the sensor is bad.

well the problem is kindda wierd becuase I replaced the oil sender due to the fact that the needle was bouncing all over the place and that is when I discovered the loose cable. I did not connect the cable because I did not know wht the cable was for. With the new sender, the pressure stabilized at 40psi on idle and would jump to 75psi at 4000rpms.Then I connected the cable and oil pressure still read 40psi in idle but if I reved the engine a bit in the water I would get that alarm.

After I disconnected the cable to not get the solid alarm the oil gauge started to bounce around all over the place again if I rev the engine to more that 2000 rpms in the water.

with the muffs and reving the engine in my driveway I do not get the alarm.
