Have Boat Questions? Ask a Boat Repair Expert.
Hi Jim, my name is Jason.
I read what you wrote. Is there a history to this problem?
Is this an intermittent issue or does it happen every time?
I'm not going to call until I know more about what's going on.
Hi Rick, my name is Jason.
It's ultimately the pressure control valve inside of the oil pump that controls engine oil pressure. What I would do In the shop is disconnect the oil pressure sending unit and plumb in a mechanical gauge, run the boat, and see if the mechanical gauge does the same thing or not. If it does not, and if the mechanical gauge reads fairly steady, then the engine has a bad sending unit on it. If the oil pressure reads the same/does the same thing on the mechanical gauge then the engine would need a new oil pump. Does that make sense to you?
I don't know what happened but that reply was not meant for you. I will opt out.
