I Think My Oil Pumps Gone Bad!

We hit the lake today and my oil pressure dropped to zero. The Valves started ticking signaling that the lifters weren't getting any oil. Had to be towed in. Took it by the shop where Monte has his boat and he said that either the oil pump is bad or it spun a bearing. The time before last my dad was driving it and he noticed that the oil pressure gauge kept fluxuating while at a costant speed. Could this be an indication that the pump was going bad. And I had been hearing a squeeking noise and thought that is was the belt. Could that have also been caused be the oil pump going bad? I am going to get it in the shop Saturday and start unhooking everything so we can hoist it out. I'm hoping it's the oil pump and not a spun bearing. Anyone experience this before?

Could it simply be the guage that has gone bad?

Or the sending unit is bad, I'd check them first, before disconnecting everything.

I don't think I would have taken it by a shop if it would have been running fine. We had to be towed in.

As you know this is my first inboard. Could you describe to me what the sending unit is?

Did the engine die or did you shut it down to prevent further damage?

It is a oil pressure sensor that is threaded into the block and sends a voltage signal to the pressure gauge.

I shut it off to prevent future damage.

Sounds like the pump to me.

Hopefully somebody who knows the inside of these engins better than me can help.

Good luck!
