The one on the left is the knock sensor...the one on the right under the one you circled that looks like a little canister should be oil pressure so the one you circled on the right should be oil temp

Didn't see that one...good call

that is correct

What they said ^^^^^^^^^
The green circled one is the oil psi sender and the wire for it is not visible and on the bottom of the silver canister.
It is T'd together with the oil psi alarm sensor which has the tan/blue wire.

Thank you guys for the help. Going to be tight replacing it.

^^^^^ if you are changing your oil temp sensor out, would you mind sending me your old one to Texas because I am having all TEMP related sensors that are on marine engines made in the USA and better quality along with better accuracy currently. .THANKS

i thought the oil pressure sensor is that big ass canister off the bottom of the sensor circled in green

i have a manual at home and can look after work
