Oil pump

[Caldy]

Hi, thanks for your sound advice. I'm thinking it's the oil pump due to little oil at the tappets, I've changed the sensor/switch, new spin on oil assembly and filter. Tested pressure.
When I turn on ignition the oil warning light is off. Any advice would be grateful.

Didn't need to test it as engine was out of the boat
thats a good shout, I'll test it next time I'm on the boat. Cheers
